As a outside observer, NAND and DRAM prices have skyrocket ed with the AI infrastructure boom just as the China-based fabs are coming online.
It is wise for these Chinese fabs to eventually use a very aggressive dumping strategy to price well below cost push out other players forever, especially in DRAM.
But right now it seems they can max out their supply capacity without selling below cost.
Appears to me like China's endless state led (often unproductive) investment in semiconductor manufacturing subsidies (for decades) is about to pay off with some industry dominance soon.
That's the most obvious example of failure of Chinese central planning. That and one child policy were abysmal failures that resulted from shoddy science coupled to effective central authority.
Look at the 12/13/14th 5 year plan (the most recently passed). Do you think they achieved their goals?
If your headcanon is that the CCP is inept because they caused crop failures 60 years ago... you could stand to take a look at what they're doing today.
I guess the summary is as simple as: Good five year plans are great, bad five year plans are terrible.
There are sooo many variables in how one could go about making and executing five year plans. They must have figured out a couple of things that tend to work.
If your headcanon is "5 year plans are great because some chinese supplier has cheap DDR-4", I would submit a gentle introduction to history is helpful (i.e. we took a couple irrational great leaps forward from cheap DDR-4 => China owns the RAM market => 5 year plans are the way to go)
Dumping is when you sell things for below cost. It is not dumping when you charge a 500% markup instead of a 1000% markup, even if the market is currently selling at that markup.
> It is wise for these Chinese fabs to eventually use a very aggressive dumping strategy to price well below cost push out other players forever, especially in DRAM.
Crucial's departure from the consumer market left such a gaping hole, that CXMT doesn't even need to push other players out to gain a footing.
No, they raise price because they can and demand isn’t showing signs of stopping despite increased prices. This won’t affect whether there’s a shortage or not, besides we’re not talking direct to consumer float product, they inked commitments.
If they didn’t have a documented history of running cartel price fixing schemes for LCD/OLED display tech, NAND, and DRAM, I’d maybe agree with you but we have the history. They cry every time about China ‘dumping’ for not going along with the racket.
Can chose to increase production or embrace the scarcity. The later might look delicious on paper. More profit, less effort, less short term risk. All you have to do is ignore the whale in the room.
They are increasing production. Fabs take multiple years to come online. The modern semiconductor industry moves only very slowly and at very great cost.
The downside in general is that other countries lose production capacity in steel, heavy industry, semiconductors, machine tools etc - industries that took decades to build and can't be easily replaced.
Also they gradually lose the ability to meaningfully innovate in those sectors because there's no grounding against production reality anymore.
This has geopolitical consequences further down the line.
As though moving production to China wasn’t something the West did intentionally.
And now continues to push manufacturing out of Western countries by, for example in the UK and Germany, and Australia too, making electricity and gas so expensive it becomes cost prohibitive to manufacture much at all.
> The downside in general is that other countries lose production capacity in steel, heavy industry, semiconductors, machine tools etc - industries that took decades to build and can't be easily replaced.
That's not really what happens though. You don't actually "lose" capacity, you just move to higher-valued special niches within the overall industry because (1) you can afford to, while low-cost competitors can't and (2) you can no longer expect to be the lowest-cost supplier for the bulk of the market. That's a win-win development and something to be encouraged.
> You don't actually "lose" capacity, you just move to higher-valued special niches within the overall industry
That's not what people mean by "lose" capacity.
Suppose DRAM companies expand capacity because prices are high, then demand levels off, the price crashes, and they all go out of business except for the one in China which gets a government bailout. That's fine, right? We're not interested in making DRAM, that's a fungible commodity, we want to make iPhones or something. (They make those too anymore, but never mind that.)
What happens now if China restricts what you can buy to give an advantage to their own companies who are trying to displace you in the higher-valued special niches? Or just raises the price for you and not them? What if there's a trade war? Or a conventional war?
When you still have a domestic industry, you go to them and have a source for the commodity. If only one country becomes the sole global supplier and that country isn't even particularly friendly, that's bad.
The domestic industry is still there, only instead of mass-market DRAM it has started making higher-valued varieties of the same stuff. If there's a trade war, they can easily reconvert to making the mass-market stuff, just at much higher cost. You can't expect more than that, since they never really were as big or as low-cost as the lowest cost suppliers can be in normal times. That's not "losing" capacity, it's just acknowledging that you can't create capacity out of thin air.
We don't want to spin up wafer fabs because, historically, they had a tendency to turn into Superfund sites. That's why the more modern approach is to build the fab in the middle of a frickin' desert.
Historically, but likely not anymore. You wouldn't be allowed to casually poison the ground in a Western factory anymore and we have the technology to keep the environment mostly clean. I don't even see it being very expensive compared to other fab costs. Have a sealed floor and proper waste / exhaust processing, don't spill in the first place. Things must be extremely well controlled anyway.
Different types of DRAM can literally be made from the same already-etched wafer. The DRAM bits themselves don't change at all. What's different between DDR4, DDR5, and HBM is the IO interface to the chip. Changing this does not require significant retooling or relearning.
> The DRAM bits themselves don't change at all. What's different between DDR4, DDR5, and HBM is the IO interface
That's not completely accurate - since the bw between these are different, the routing and therefore propagation delays for DDR4 won't allow it to magically be used as DDR5 or HBM.
If you design for the most strict timings, then sure.
They're still at somewhat of a process disadvantage, but they have demonstrated an ability to produce DDR4 on older processes than it's typically been produced on. So it stands to reason that their process disadvantage will not stop them from producing DDR5 at scale. Their DDR5 will just use a little more silicon, and squeeze the jigglyness from a few more electrons, but in this market, who cares if RAM cost 15% more to make and was 15% less efficient to run, if it's available to purchase at all.
They will eventually eat everything while they laugh at us. Why would you build a rail network if it isn't profitable? Why build anything if it isn't profitable? Why would you even house people if the profit isn't guaranteed to be as big as other sectors?
Everyone wanted denarius then escudos then guilders then pounds then dollars and soon yuan. They make stuff over there, you can buy it with yuan.
I think India might come after that but Africa is sure to follow. Give it a few hundred years.
> steel, heavy industry, semiconductors, machine tools
the question is if single country can carry all these industries at loss for prolonged period of time.
Another approach is to rely on international supply chain and speed of innovation, we can't produce steel domestically profitably today, fine, we may buy it from diversified international supplier network, and rebuild it fast tomorrow if needed using new tech, and focus on many other high margin verticals, instead of putting many billions of resources into infra which could be obsolete tomorrow.
Agree, worth analysing what is genuinely commodity.
There are more elements to it though which can be sort of hard to explain.
There are whole cultures and ways of thinking built around production. The children of engineers who worked on xyz v1.0 have a genuine advantage when its time to work on xyz v2.0. There is a lot of tacit knowledge in these engineering fields and you have a huge advantage in knowledge retention if you can maintain unbroken chains of succession.
You can't achieve the top levels of ability (decades of experience, generational knowledge) if you are whip-sawing production to and fro across the globe every 10 years.
There are also cross pollination effects. Being in the same community with as many related fields as possible (co-located) is what drives cross-pollination and mobility of ideas and people between industries.
Think how many countries have tried to copy "silicon valley" and failed, and _why_ they failed.
What I'm saying is that technology is built by _people_ and there are human reasons why having local capacity is beneficial for all the related industries in the area.
> The children of engineers who worked on xyz v1.0 have a genuine advantage when its time to work on xyz v2.0.
my point is that other children with no extremely heavy investments into perl v1.0, will have some skills in c++ v1.0 and python v1.0, and will have advantage in adapting Tensorflow v1.0, which is more valuable than skills in perl v2.0. Heavily investing in one industry you sacrifice some flexibility.
So, this is multifactor analysis, lets say wise American people will elect me as next president, I would create list of industries, assign metrics (national security importance, potential revenue in 5y from now, impact on other industries, potential margin, risks of failure, etc), then build some formula which aggregate those metrics into single, and base on final metric allocate weighted funds to support N top industries.
First, they're not selling at a loss; the huge price increases have allowed them to push aggrssively in the legacy markets. They're making "slightly smaller" profits than other manufacturers (of which there are now very few).
Second, they can drive out all competition and then have a captive audience for whatever prices they want, as the barriers to entry in these markets are very high. This is essentially what's happened with all higher-end manufacturing in the west over the past 30+ years.
I don't know if it's still a thing, but China was getting a lot of heat about a decade ago for purposefully devaluing their currency to make their exports more attractive.
They kind of had to do this, because their large amount of exports were pushing the value of it up compared to others.
Amazon was wildly profitable on a unit cost basis from relatively early on. They didn’t show profits on paper because they reinvested everything into their capital buildout to reduce costs even more.
They are? Most of what VC funded companies do has been done before at a smaller scale, often with less polish and at a higher price.
VC money is used to scale up, cut costs with scale, capture markets, and then usually prices go up later depending on the economics.
The Chinese state is basically just acting as a big VC fund for Chinese manufacturing industries. A VC fund with a sovereign currency and the ability to sustain burn-mode for decades.
It doesn’t always work. There are some absurd examples of Chinese waste produced this way like “ghost cities.” But when it works it works, and at tremendous scale, and they can just dominate entire industries.
It's questionable whether the ghost cities truly exist though. I was under the impression they were a product of China's bizarre savings and investment market, and that a lot of them have since filled up?
It's funny that you call this an "very aggressive dumping strategy" while AI vendors are doing the same but with even greater losses and on a much larger scale.
It's all simply a fight for market share.
The original sin is the existing DRAM vendors selling their entire (spare) capacity to the likes of OpenAI.
Can we please stop with this irritatingly persistent myth? AI companies, at least the big ones, do not sell inference at a loss - far from it. This has been debunked and explained many times and yet it keeps being repeated.
The numbers aren't public but most guesses I've heard are that Anthropic's markup is around 50% on average, and that if considered in isolation, most models are profitable overall. The constant losses are instead due to training the next models, which will also eventually recoup but later, and forward capex investment.
This idea that big AI companies are normally and systematically selling inference at a loss as some kind of market share strategy is just not supported by the facts.
> It is wise for these Chinese fabs to eventually use a very aggressive dumping strategy to price well below cost push out other players forever, especially in DRAM.
It's not dumping, it's the opposite.
Sam Altman's stunt has created massive amounts of fictitious demand (OpenAI isn't using those wafers it's ordering) and triggered massive panic-buying from everyone else.
Prices are arteficially high, this has turbocharged China's fab and R&D budgets as you observe.
> is about to pay off with some industry dominance soon.
They're not looking to dump the semiconductor markets. They're looking to invade Taiwan.
All this buildout in their semiconductor industry is to detach themselves from the western semiconductor industry that will either sanction them if they invade Taiwan, or in the case of TSMC, suffer major damage in the ensuing conflict.
That the collapse/destruction of the Taiwanese semiconductor and electronics industries will utterly ruin the western tech industry is somewhere between a happy coincidence and acceptable collateral damage to them. No dumping required.
I realize Intel has done some serious ball dropping over the past two decades but you do realize the US has on shore cutting edge fabs, right? It's only luxury consumer electronics and the highest end corporate gear that use cutting edge nodes to begin with.
Disruption of the cutting edge would certainly wreak havoc on the pricing and specs of high end luxury electronics but that would hardly be the end of the world. I still use a desktop with DDR3 on a daily basis (granted the GPU is much newer with GDDR6) and my laptop is from the early era of DDR4 ...
> CXMT is in the process of converting wafer capacity equivalent to about 20 percent of its total DRAM output — some 60,000 wafers per month — at its Shanghai plant to the fourth-generation HBM3 chip production
I've heard that Samsung's business practices can be quite predatory. Basically if you have cool tech and you try to sell it to Samsung, you'll often get a few meetings and then they will go silent and then what you were trying to sell them will be offered by them as a new product about a year later. At least this was the situation like a decade ago.
I think this is because they are a huge conglomerate and there are divisions and groups that specialize in everything and their (Samsung) culture is to do everything as much as possible in house.
> you'll often get a few meetings and then they will go silent and then what you were trying to sell them will be offered by them as a new product about a year later
This is table stakes in any business anywhere. any time you talk to investors or suppliers you risk them using this information so you better be careful have lawyers and set up correctly.
The caveat is of course when Chinese companies do this your lawyers can do nothing while in a developed country you can have some recourse
But even if Samsung was super predatory business wise it is beside the point. They both get subsidies and de facto are close to their governments so you have to look at what their governments do. Maybe you like what CCP is doing, it's your choice
Apple has planned to explore cooperation with Chinese memory chip manufacturers Yangtze Storage (YMTC) and Changxin Storage (CXMT) to strive for more favorable supply contracts [from the big three]
That explains the cheap DDR4 DIMMs on AliExpress. Can get 2x 16GB DDR4-3200 DIMMs for A$252 delivered to Australia. A local PC store has same spec “name brand” RAM for around $380-$400.
DDR4 going from $1.35 to $11.50 in a year shows this market was already distorted before CXMT showed up.
Legacy DRAM is still over half of Samsung and SK hynix's production capacity. That's where the volume pain actually lands while they're betting everything on HBM4.
A near 10 times price rise of legacy chips and surely a lot higher profit increase couldn't motivate SKamsunix to increase their capacity for that segment, even more, they proudly informed the market about their decision to stop making DDR4 at the end of this year... to focus on even higher margin products.
But they aren't going to stop whining about China, no matter how much pain the market experiences.
Back in the 1990’s everyone had to have a unix workstation for unclear reasons (why not run Linux for < 10% the cost?).
There were crazy bubble economics schemes that meant doomed startups got unix boxes for free.
When the bubble popped, the workstation vendors hit a triple whammy: Inferior $/perf, unlimited used inventory at low prices, and an economic downturn.
The same exact thing is happening now, except the hardware is being jammed into data center models.
Anyway, when the bubble pops, people making affordable consumer stuff will be fine (like this CXMT company).
People that went all-in on firing all non-hyperscaler customers (like micron/crucial) will find they’re building the wrong chips for end-user devices, there is no server market anymore (for a few years), and they have a total addressable market of maybe 1000 distressed companies, globally.
I predict the people making these decisions and destroying their companies to juice Q2 2026 financial outlook numbers will genuinely be surprised when the bankruptcies start.
This feels like a classic business blunder. Focus hard on a single business segment, leaving an opening in the market for your competitors. Not because it wasn't profitable, but because it wasn't profitable enough for you, right now. Only downside is that now you've created an opening for a new player in the market.
This feels like a short coming of western business/stock market thinking. Focusing on profit within the next few quarters, and not caring about the longer term consequences. For all it's flaws and shady business practises at least China can think beyond a single fiscal year.
Ok but this is how the market is supposed to work. If the incumbents aren't doing what their customers want, then competitors can rise and fill the gap and compete.
This isn't a shortcoming, it's a competitive market working as intended.
Who said I thought businesses would always make the right move?
Businesses blunder. "The market" is just a set of observations, including that competitors will tend to take advantage of those blunders. It is not a failure of the market that businesses have blundered, nor surprising that it will happen occasionally, and neither I nor mrweasel implied otherwise.
Lets not forget there is no competitors. There is one competitor- the chinese state, one huge company willing to subsidize any endeavor that will help it fmgain more marketshare with already captured markets.
NO you see, we have to hate Chinese companies because they are unfair competitors since they get state funding from the Chinese government, unlike Intel, Micron, TSMC, ASML, Samsung who don't get state funding from the US, EU, Taiwan, ROK ... oh wait.
Scratch that, we have to hate Chinese companies because they do business with the Chinese military, unlike Intel, Nvidia, Samsung who don't do business with the US and ROK military ... oh wait.
I know you are being sarcastic but the reason why we have to hate Chinese is simply because the standard of living of Americans depends on China not succeeding, simple as that.
Does it, though? If anything it seems like the opposite: China's success had directly enabled my standard of living as an American to be as high as it is.
I suppose it'd be true that the standard of living of some Americans depends on China not succeeding — specifically, those Americans who own corporations competing with Chinese firms — but I think they'll survive just fine with only 10 yachts instead of 15.
Well then hey can just say THAT, instead of coming up with hypocritical BS that doesn't pass the smell test. People internationally have enough IQ to see through the double standards BS, especially since youtube is a thing.
And the standard of living of working class Americans has been on a steady decline since Reagan by the hand of US administrations, not by the hand of CHina.
This isn't defending anyone's standard of living, it's defending profits of domestic monopolies like Micron, who indulge in state subsidies from US taxpayers and then fuck then over on prices.
CXMT sells the vast majority of their bits at the prevailing market rate, just like everyone else. They are adding capacity as quickly as they can, with a 5-10 year planning horizon, just like everyone else. It’s really not that deep!
Yes of course their messaging to customers and the investment community is that they will be rational and measured in their investments. In reality, they are adding capacity as quickly as possible as margins are too high. However, capacity addition leading edge semiconductor manufacturing has a multi-year lead time.
> In reality, they are adding capacity as quickly as possible [...]
Even if we ignore the fact that you can't build out factories in secret, this would be securities fraud by publicly listed companies.
> ...as margins are too high
This is not the first RAM boom-bust cycle, and memory makers are an actual cartel convicted of coordinating in the past - none if them are going to break rank when they can invest the minimum and reap outsized benefits. Also, no one wants to invest in additional capacity when the bottom can fall out at anytime, and shareholders demand your head- not even the AI companies want to bear that risk, which is saying something.
PRC asked them to curtail DDR4 production so they didn't bottom out the market a year or two ago, and to focus on latest gen development, like HBM. They were the world leader in cost efficient DDR4 production at the time.
It's not really a blunder though. Given that total capacity is tightly constrained, Samsung and SK Hynix are happy to focus on what they do at their best and with the highest margins. Why shouldn't they supply the HBM market?
It's putting all eggs in one basket. If/when the higher-margin category collapses, they'll have no fallback. Imagine Chevrolet had discontinued Impalas and other low-margin cars, and switched to Corvettes during the pandemic
Even if there's a collapse in the high-margin market (I don't think anyone is expecting this right now), it will be slow and telegraphed in advance, giving them plenty of time to refocus on lower-margin products.
There is really nothing about the stock market that means only thinking about the mext few quarters. See all the losses on the profit and loss statements of AI tech giants, or, say, game console companies? Why are their stocks still valued so highly during these periods? The answer: investors are thinking long term.
It is really impossible to have quality long term thinking without capitalization accounting and similar instruments that come out of the "wester" system of business that chinese free enterprise gladly and speedily copied when it was made free.
I think the sentiment here is about management's tie of bonuses to near-term stock performance. Maybe not about the market itself, I agree with your view on investors want long term gains over short term fluctuations mostly.
Because that’s just the price for the dies, still need packaging, integration and then retail distribution. Also raw BOM is like 1/5th of the retail price usually.
You can buy oil on the market and take delivery, yes. Figuring out the logistics (tanker trucks, rail cars, storage tanks etc) will also be your problem though.
Commodities markets aren’t like eBay, nobody is just going to FedEx you a barrel of oil.
Has DDR5 caught up to DDR4 latency yet? I remember it was worse at least in the beginning. There's more bandwidth per channel but a hw design can always add more channels for the desired BW. Not so for latency.
and unfortunately increase latency even more with registered DIMMs. Comparing bandwidth increase (50 GB/s) to the stagnated latency (~80..120 ns total, less than ~0.1 GB/s) over last decades, I'm wondering, whether one still can call today's RAM random memory (though sure it can be accessed randomly). Similar to hard disk drives. Up to 300 MB/s sequentially but only up to less than 1 MB/s 4KB random (read).
I was wondering when people would find out about CXMT. I wish them luck and hope the US doesn't sabotage them. We need diversity and competition right now.
It might be very effective marketing. The big non-Chinese OEMs trust and use Korean and Japanese DRAM, and they might have been unwilling to put DRAM from CXMT into their products. (CXMT is newish, does not have access to ASML gear, which ASML would like you to believe makes it harder to make high-quality DRAM, DRAM is historically not a very large fraction of the cost of most non-huge-memory machines, and a bad DIMM is an expensive mistake for a company like Dell or HPE that is on the hook for repairs.)
But now CXMT seems to have gotten at least Dell, HP (I wonder if the article meant HPE), Acer and Asus to buy and attempt to qualify samples. If CXMT lands some serious purchasing agreements while still selling well above cost, that’s a win for them.
Does the last part of your comment explain it? They need revenue to expand capacity and the market has opened up a window to become a bigger supplier while still being profitable.
Because market rate is a 400%+ markup right now and not everyone is a greedy American kleptocrat with a diagnosable addiction to extracting every possible cent of wealth on the planet within a single fiscal quarter.
Is there a reason GPU's don't use insane "blocks" of sdcard slots (for massively parallel io) so the model weights don't need to pass through a limited PCI bus?
Yes. Let's do the math. The fastest sd cards can read at around 300 MB/s (https://havecamerawilltravel.com/fastest-sd-cards/). Modern GPUs use 16 lanes of PCIe gen 5, which is 16x32Gb/s = 512Gb/s = 64 GB/s. Meaning you'd need over 200 of the fastest SD cards. So what you're asking is: is there a reason GPUs don't use 200 SD cards? And I can't think of any way that would work
SD is obviously the wrong interface for this but "High Bandwidth Flash" (stacked flash akin to HBM) is in development for exactly this kind of problem. AMD actually made a GPU with onboard flash maybe a decade ago but I think it was a bit early. Today I would love to have a pool of 50GB/s storage attached to the GPU.
Oh definitely. The AMD past product just stuck 4x m.2 slots onto the board. Today that approach would be 50-60 GB/s read speed which would be useful enough for something that any of the vendors could build with existing components.
One thing to note, those aren't the fastest SD cards, those are the fastest UHS-II SD cards. The future is SD Express and you can already get microSDs at 900 MB/s.
Some years ago I realized that if I had oodles of money to spend I would totally get someone to make a PCIe card with like several hundreds microSD cards on it.
You can buy vertical microSD connectors, so you can stack quite a lot of them on a PCIe card. Then a beefy FPGA to present it as a NVMe device to the host.
Goal total capacity, as you can put 1TB cards in there. And for teh lulz of course.
The next gen inference chips will use High Bandwidth Flash (HBF) to store model weights.
These are made similarly to HBM but are lower power and much higher capacity. They can also be used for caching to reduce costs when processing long chat sessions.
As far as I understand, the "entity list" you are referring to is part of the "Export Administration Regulations", so it restricts sales from the US to restricted entities, not the other way around.
It ain't the price raise that's the mistake (even if that's what's currently painful for those of us looking to buy RAM). It's the willingness to only raise prices, and not meaningfully expand production, that's the mistake.
But since when? There are public announcements about new energy deals since summer 2024. But I'm missing any information about similar RAM/NAND/HDD deals back then, so that corresponding shortages could be only for short time until, say, summer 2026.
OTOH, now I read small Taiwanese manufacturers who are left out of the Nvidia supply chain are reverting to DDR4 motherboards because of the DDR5 shortage. Strange times.
The pertinent question, then, is who's gonna eat China's lunch?
My guess would be south/southeast Asia (India and Vietnam seem especially promising), but if the US was smart it'd put its efforts fully toward as many infrastructure investments and trade agreements and immigration agreements as possible to create a pan-American economic union. We have the resources and technology to turn every country in North and South America into an industrial and technological powerhouse. We have the resources and technology to finally conquer the Darién Gap and connect North and South America with highways and high-speed rail. We have the resources and technology to go on the offense against drug cartels (while also eliminating the failed border controls and drug prohibitions that keep those cartels in business in the first place).
If we're gonna be imperialists, then by golly let's at least be productive about it.
China's big. It has a long way to go before all of it becomes developed enough that they have to worry about someone else eating their lunch.
And Latin American nations can't get started on economic development because their governance sucks. It's actually a decades-old problem, and not one that the U.S. can do much about. The one country that probably has the best shot right now is Argentina, let's see how they do.
As a outside observer, NAND and DRAM prices have skyrocket ed with the AI infrastructure boom just as the China-based fabs are coming online.
It is wise for these Chinese fabs to eventually use a very aggressive dumping strategy to price well below cost push out other players forever, especially in DRAM.
But right now it seems they can max out their supply capacity without selling below cost.
Appears to me like China's endless state led (often unproductive) investment in semiconductor manufacturing subsidies (for decades) is about to pay off with some industry dominance soon.
Like the electric vehicle sector.
It's amazing what can be achieved when you can plan 5 years in advance, instead of just making the line go up for the next quarter.
History is littered with the corpses of those slaughtered by the millions in the name of great leader’s 5 year plans.
https://en.wikipedia.org/wiki/Great_Leap_Forward
That's the most obvious example of failure of Chinese central planning. That and one child policy were abysmal failures that resulted from shoddy science coupled to effective central authority.
Look at the 12/13/14th 5 year plan (the most recently passed). Do you think they achieved their goals?

And you don’t think short term profit chasing has a death count?
Not five, but likely twenty-five. Not specific plans but attention: situation changes all the time, but the interest remains.
Don’t forget all the times those plans fail because the world did not turn out to be what you thought it would.
Dumping is when you sell things for below cost. It is not dumping when you charge a 500% markup instead of a 1000% markup, even if the market is currently selling at that markup.
> It is wise for these Chinese fabs to eventually use a very aggressive dumping strategy to price well below cost push out other players forever, especially in DRAM.
Crucial's departure from the consumer market left such a gaping hole, that CXMT doesn't even need to push other players out to gain a footing.
It's more like everyone else abandoned the market, and CXMT realised it was free real estate.
How's it dumping below cost when hey can simply sell for 100% margins instead of western makers selling for 400%.
It's easy to misread, but they're not arguing that. Note the "eventually" and "but right now".
Because only western companies are allowed to make massive profits at the expense of entire nations, it's not greed when they do it apparently.
Is it not the case that they're raising price in response to demand? Ie. if they kept the price low, they'd be perpetually out of supply?
No, they raise price because they can and demand isn’t showing signs of stopping despite increased prices. This won’t affect whether there’s a shortage or not, besides we’re not talking direct to consumer float product, they inked commitments.
If they didn’t have a documented history of running cartel price fixing schemes for LCD/OLED display tech, NAND, and DRAM, I’d maybe agree with you but we have the history. They cry every time about China ‘dumping’ for not going along with the racket.
Can chose to increase production or embrace the scarcity. The later might look delicious on paper. More profit, less effort, less short term risk. All you have to do is ignore the whale in the room.
They are increasing production. Fabs take multiple years to come online. The modern semiconductor industry moves only very slowly and at very great cost.
I personally fail to see the downside of any manufacturer selling forever at a loss, except for the manufacturer itself.
You become dependent on the supplier.
The downside in general is that other countries lose production capacity in steel, heavy industry, semiconductors, machine tools etc - industries that took decades to build and can't be easily replaced.
Also they gradually lose the ability to meaningfully innovate in those sectors because there's no grounding against production reality anymore.
This has geopolitical consequences further down the line.
Blame China.
As though moving production to China wasn’t something the West did intentionally.
And now continues to push manufacturing out of Western countries by, for example in the UK and Germany, and Australia too, making electricity and gas so expensive it becomes cost prohibitive to manufacture much at all.
> The downside in general is that other countries lose production capacity in steel, heavy industry, semiconductors, machine tools etc - industries that took decades to build and can't be easily replaced.
That's not really what happens though. You don't actually "lose" capacity, you just move to higher-valued special niches within the overall industry because (1) you can afford to, while low-cost competitors can't and (2) you can no longer expect to be the lowest-cost supplier for the bulk of the market. That's a win-win development and something to be encouraged.
> You don't actually "lose" capacity, you just move to higher-valued special niches within the overall industry
That's not what people mean by "lose" capacity.
Suppose DRAM companies expand capacity because prices are high, then demand levels off, the price crashes, and they all go out of business except for the one in China which gets a government bailout. That's fine, right? We're not interested in making DRAM, that's a fungible commodity, we want to make iPhones or something. (They make those too anymore, but never mind that.)
What happens now if China restricts what you can buy to give an advantage to their own companies who are trying to displace you in the higher-valued special niches? Or just raises the price for you and not them? What if there's a trade war? Or a conventional war?
When you still have a domestic industry, you go to them and have a source for the commodity. If only one country becomes the sole global supplier and that country isn't even particularly friendly, that's bad.
The domestic industry is still there, only instead of mass-market DRAM it has started making higher-valued varieties of the same stuff. If there's a trade war, they can easily reconvert to making the mass-market stuff, just at much higher cost. You can't expect more than that, since they never really were as big or as low-cost as the lowest cost suppliers can be in normal times. That's not "losing" capacity, it's just acknowledging that you can't create capacity out of thin air.
No, the domestic industry stagnates (at best) or disappears (at worst).
You can't just spin up a 2nm wafer fab when the latest you've been running is a 300nm process.
Compare: US shipbuilding industry to China or SK.
We don't want to spin up wafer fabs because, historically, they had a tendency to turn into Superfund sites. That's why the more modern approach is to build the fab in the middle of a frickin' desert.
Historically, but likely not anymore. You wouldn't be allowed to casually poison the ground in a Western factory anymore and we have the technology to keep the environment mostly clean. I don't even see it being very expensive compared to other fab costs. Have a sealed floor and proper waste / exhaust processing, don't spill in the first place. Things must be extremely well controlled anyway.
> If there's a trade war, they can easily reconvert to making the mass-market stuff
Factories, tooling, supply chains, and engineering knowledge aren't fungible in the way they would need to be for your statement to be true.
Different types of DRAM can literally be made from the same already-etched wafer. The DRAM bits themselves don't change at all. What's different between DDR4, DDR5, and HBM is the IO interface to the chip. Changing this does not require significant retooling or relearning.
> The DRAM bits themselves don't change at all. What's different between DDR4, DDR5, and HBM is the IO interface
That's not completely accurate - since the bw between these are different, the routing and therefore propagation delays for DDR4 won't allow it to magically be used as DDR5 or HBM.
If you design for the most strict timings, then sure.
Does that mean CXMT is one inch away from also eating into the DDR5 market?
They're still at somewhat of a process disadvantage, but they have demonstrated an ability to produce DDR4 on older processes than it's typically been produced on. So it stands to reason that their process disadvantage will not stop them from producing DDR5 at scale. Their DDR5 will just use a little more silicon, and squeeze the jigglyness from a few more electrons, but in this market, who cares if RAM cost 15% more to make and was 15% less efficient to run, if it's available to purchase at all.
They will eventually eat everything while they laugh at us. Why would you build a rail network if it isn't profitable? Why build anything if it isn't profitable? Why would you even house people if the profit isn't guaranteed to be as big as other sectors?
Everyone wanted denarius then escudos then guilders then pounds then dollars and soon yuan. They make stuff over there, you can buy it with yuan.
I think India might come after that but Africa is sure to follow. Give it a few hundred years.
> If there's a trade war, they can easily reconvert to making the mass-market stuff, just at much higher cost.
"easily" is doing a lot of work in that sentence. Depending on the good and what they switch to making, this may neither be easy nor quick.
Higher valued varieties, or just higher priced varieties, that no one wants to buy?
> steel, heavy industry, semiconductors, machine tools
the question is if single country can carry all these industries at loss for prolonged period of time.
Another approach is to rely on international supply chain and speed of innovation, we can't produce steel domestically profitably today, fine, we may buy it from diversified international supplier network, and rebuild it fast tomorrow if needed using new tech, and focus on many other high margin verticals, instead of putting many billions of resources into infra which could be obsolete tomorrow.
This is fine as long as the supply chain is, in fact, diversified.
sure, looks like more analysis is needed to check which verticals are diversified and which are not, instead of throwing blanket list of everything.
Agree, worth analysing what is genuinely commodity.
There are more elements to it though which can be sort of hard to explain.
There are whole cultures and ways of thinking built around production. The children of engineers who worked on xyz v1.0 have a genuine advantage when its time to work on xyz v2.0. There is a lot of tacit knowledge in these engineering fields and you have a huge advantage in knowledge retention if you can maintain unbroken chains of succession.
You can't achieve the top levels of ability (decades of experience, generational knowledge) if you are whip-sawing production to and fro across the globe every 10 years.
There are also cross pollination effects. Being in the same community with as many related fields as possible (co-located) is what drives cross-pollination and mobility of ideas and people between industries.
Think how many countries have tried to copy "silicon valley" and failed, and _why_ they failed.
What I'm saying is that technology is built by _people_ and there are human reasons why having local capacity is beneficial for all the related industries in the area.
https://atlas.hks.harvard.edu/
> The children of engineers who worked on xyz v1.0 have a genuine advantage when its time to work on xyz v2.0.
my point is that other children with no extremely heavy investments into perl v1.0, will have some skills in c++ v1.0 and python v1.0, and will have advantage in adapting Tensorflow v1.0, which is more valuable than skills in perl v2.0. Heavily investing in one industry you sacrifice some flexibility.
So, this is multifactor analysis, lets say wise American people will elect me as next president, I would create list of industries, assign metrics (national security importance, potential revenue in 5y from now, impact on other industries, potential margin, risks of failure, etc), then build some formula which aggregate those metrics into single, and base on final metric allocate weighted funds to support N top industries.
First, they're not selling at a loss; the huge price increases have allowed them to push aggrssively in the legacy markets. They're making "slightly smaller" profits than other manufacturers (of which there are now very few).
Second, they can drive out all competition and then have a captive audience for whatever prices they want, as the barriers to entry in these markets are very high. This is essentially what's happened with all higher-end manufacturing in the west over the past 30+ years.
If you actually believe this, then what is your explanation for a manufacturer to do this?
Do you think they are just stupid?
Microsoft gave away Internet Explorer at a loss, and what happened to internet standards?
the currency eventually collapses
I don't know if it's still a thing, but China was getting a lot of heat about a decade ago for purposefully devaluing their currency to make their exports more attractive.
They kind of had to do this, because their large amount of exports were pushing the value of it up compared to others.
> It is wise … to price well below cost push out other players forever
I challenge you to name a single successful example of this that isn’t state enforced.
Uber
Amazon?
Amazon was wildly profitable on a unit cost basis from relatively early on. They didn’t show profits on paper because they reinvested everything into their capital buildout to reduce costs even more.
I thought Amazon was selling quite a few items at a loss to undercut competition early on?
All VC funded companies that release free or underpriced products and services, capture market share, then raise prices or enshittify?
The entire business model of VC funded tech?
Typically, VC funded firms are inventing new markets entirely.
Simply overcoming startup capital costs is not the argument being made when folks claim dumping.
They are? Most of what VC funded companies do has been done before at a smaller scale, often with less polish and at a higher price.
VC money is used to scale up, cut costs with scale, capture markets, and then usually prices go up later depending on the economics.
The Chinese state is basically just acting as a big VC fund for Chinese manufacturing industries. A VC fund with a sovereign currency and the ability to sustain burn-mode for decades.
It doesn’t always work. There are some absurd examples of Chinese waste produced this way like “ghost cities.” But when it works it works, and at tremendous scale, and they can just dominate entire industries.
It's questionable whether the ghost cities truly exist though. I was under the impression they were a product of China's bizarre savings and investment market, and that a lot of them have since filled up?
It's funny that you call this an "very aggressive dumping strategy" while AI vendors are doing the same but with even greater losses and on a much larger scale.
It's all simply a fight for market share.
The original sin is the existing DRAM vendors selling their entire (spare) capacity to the likes of OpenAI.
Can we please stop with this irritatingly persistent myth? AI companies, at least the big ones, do not sell inference at a loss - far from it. This has been debunked and explained many times and yet it keeps being repeated.
The numbers aren't public but most guesses I've heard are that Anthropic's markup is around 50% on average, and that if considered in isolation, most models are profitable overall. The constant losses are instead due to training the next models, which will also eventually recoup but later, and forward capex investment.
This idea that big AI companies are normally and systematically selling inference at a loss as some kind of market share strategy is just not supported by the facts.
No one sold their capacity to OpenAI. The vast majority of DRAM is transacted in what is essentially a quarterly auction.
"RAM is going to AI: OpenAI has secured up to 40% of the market."
https://globalcio.com/news/16062/
You're maybe talking about the spot market, but companies are free to make any sort of supply contract.
AI slop article
> It is wise for these Chinese fabs to eventually use a very aggressive dumping strategy to price well below cost push out other players forever, especially in DRAM.
It's not dumping, it's the opposite.
Sam Altman's stunt has created massive amounts of fictitious demand (OpenAI isn't using those wafers it's ordering) and triggered massive panic-buying from everyone else.
Prices are arteficially high, this has turbocharged China's fab and R&D budgets as you observe.
> is about to pay off with some industry dominance soon.
They're not looking to dump the semiconductor markets. They're looking to invade Taiwan.
All this buildout in their semiconductor industry is to detach themselves from the western semiconductor industry that will either sanction them if they invade Taiwan, or in the case of TSMC, suffer major damage in the ensuing conflict.
That the collapse/destruction of the Taiwanese semiconductor and electronics industries will utterly ruin the western tech industry is somewhere between a happy coincidence and acceptable collateral damage to them. No dumping required.
> utterly ruin
I realize Intel has done some serious ball dropping over the past two decades but you do realize the US has on shore cutting edge fabs, right? It's only luxury consumer electronics and the highest end corporate gear that use cutting edge nodes to begin with.
Disruption of the cutting edge would certainly wreak havoc on the pricing and specs of high end luxury electronics but that would hardly be the end of the world. I still use a desktop with DDR3 on a daily basis (granted the GPU is much newer with GDDR6) and my laptop is from the early era of DDR4 ...
Chinese investment has not been unproductive. It gave them independence so that the US could not cut them of- see Cuba.
Also moving into HBM:
> CXMT is in the process of converting wafer capacity equivalent to about 20 percent of its total DRAM output — some 60,000 wafers per month — at its Shanghai plant to the fourth-generation HBM3 chip production
Whenever China is mentioned, it's always about government subsidies, as if Samsung didn't receive government subsidies when it was developing
remind me is Samsung's source subsidies also regularly attacking every country's telecoms and infrastructure
I've heard that Samsung's business practices can be quite predatory. Basically if you have cool tech and you try to sell it to Samsung, you'll often get a few meetings and then they will go silent and then what you were trying to sell them will be offered by them as a new product about a year later. At least this was the situation like a decade ago.
I think this is because they are a huge conglomerate and there are divisions and groups that specialize in everything and their (Samsung) culture is to do everything as much as possible in house.
> you'll often get a few meetings and then they will go silent and then what you were trying to sell them will be offered by them as a new product about a year later
This is table stakes in any business anywhere. any time you talk to investors or suppliers you risk them using this information so you better be careful have lawyers and set up correctly.
The caveat is of course when Chinese companies do this your lawyers can do nothing while in a developed country you can have some recourse
But even if Samsung was super predatory business wise it is beside the point. They both get subsidies and de facto are close to their governments so you have to look at what their governments do. Maybe you like what CCP is doing, it's your choice
You mean the US? Yeah, they are.
sorry forgot Samsung is a US company
is CXMT attacking every contry?
its owner and boss
but sure if they are ordered to they will, good point too;)

That explains the cheap DDR4 DIMMs on AliExpress. Can get 2x 16GB DDR4-3200 DIMMs for A$252 delivered to Australia. A local PC store has same spec “name brand” RAM for around $380-$400.
https://a.aliexpress.com/_mssanU1
These prices are insane. I can’t believe that’s what constitutes a good deal right now.
For context, I spent $105 USD (all in) for 2x16gb DDR5 ram last April
2x48GB DDR5 for $285 last March.
Turns out I got the wrong kit for that build and had to buy another. It was too late to return it.
If you still have that wrong kit, now it's the time to sell it to make a fortune.
Brutal
DDR4 going from $1.35 to $11.50 in a year shows this market was already distorted before CXMT showed up.
Legacy DRAM is still over half of Samsung and SK hynix's production capacity. That's where the volume pain actually lands while they're betting everything on HBM4.
A near 10 times price rise of legacy chips and surely a lot higher profit increase couldn't motivate SKamsunix to increase their capacity for that segment, even more, they proudly informed the market about their decision to stop making DDR4 at the end of this year... to focus on even higher margin products.
But they aren't going to stop whining about China, no matter how much pain the market experiences.
Back in the 1990’s everyone had to have a unix workstation for unclear reasons (why not run Linux for < 10% the cost?).
There were crazy bubble economics schemes that meant doomed startups got unix boxes for free.
When the bubble popped, the workstation vendors hit a triple whammy: Inferior $/perf, unlimited used inventory at low prices, and an economic downturn.
The same exact thing is happening now, except the hardware is being jammed into data center models.
Anyway, when the bubble pops, people making affordable consumer stuff will be fine (like this CXMT company).
People that went all-in on firing all non-hyperscaler customers (like micron/crucial) will find they’re building the wrong chips for end-user devices, there is no server market anymore (for a few years), and they have a total addressable market of maybe 1000 distressed companies, globally.
I predict the people making these decisions and destroying their companies to juice Q2 2026 financial outlook numbers will genuinely be surprised when the bankruptcies start.
This feels like a classic business blunder. Focus hard on a single business segment, leaving an opening in the market for your competitors. Not because it wasn't profitable, but because it wasn't profitable enough for you, right now. Only downside is that now you've created an opening for a new player in the market.
This feels like a short coming of western business/stock market thinking. Focusing on profit within the next few quarters, and not caring about the longer term consequences. For all it's flaws and shady business practises at least China can think beyond a single fiscal year.
Ok but this is how the market is supposed to work. If the incumbents aren't doing what their customers want, then competitors can rise and fill the gap and compete.
This isn't a shortcoming, it's a competitive market working as intended.
The market doing what it's supposed to do does not negate that the market segment has only been left open because of overly myopic businesses.
Why would we think businesses will always make the right move?
They'll blunder. They'll do it even harder in the absence of competition.
Who said I thought businesses would always make the right move?
Businesses blunder. "The market" is just a set of observations, including that competitors will tend to take advantage of those blunders. It is not a failure of the market that businesses have blundered, nor surprising that it will happen occasionally, and neither I nor mrweasel implied otherwise.
The market is actively trying to solve it right now. Micron is investing $200B in new fabs. Everyone is trying to ramp up production.
Yes, identifying a problem is easy. But solving shortages in all cases requires perfect knowledge of future demand. So, good luck.
That's what modern capitalism is and it's bad for everyone
Lets not forget there is no competitors. There is one competitor- the chinese state, one huge company willing to subsidize any endeavor that will help it fmgain more marketshare with already captured markets.
Only if you don't want or need any geopolitical gradient at all.
Everyone gets mad when Chinese do capitalism...
NO you see, we have to hate Chinese companies because they are unfair competitors since they get state funding from the Chinese government, unlike Intel, Micron, TSMC, ASML, Samsung who don't get state funding from the US, EU, Taiwan, ROK ... oh wait.
Scratch that, we have to hate Chinese companies because they do business with the Chinese military, unlike Intel, Nvidia, Samsung who don't do business with the US and ROK military ... oh wait.
I know you are being sarcastic but the reason why we have to hate Chinese is simply because the standard of living of Americans depends on China not succeeding, simple as that.
Does it, though? If anything it seems like the opposite: China's success had directly enabled my standard of living as an American to be as high as it is.
I suppose it'd be true that the standard of living of some Americans depends on China not succeeding — specifically, those Americans who own corporations competing with Chinese firms — but I think they'll survive just fine with only 10 yachts instead of 15.
Well then hey can just say THAT, instead of coming up with hypocritical BS that doesn't pass the smell test. People internationally have enough IQ to see through the double standards BS, especially since youtube is a thing.
And the standard of living of working class Americans has been on a steady decline since Reagan by the hand of US administrations, not by the hand of CHina.
This isn't defending anyone's standard of living, it's defending profits of domestic monopolies like Micron, who indulge in state subsidies from US taxpayers and then fuck then over on prices.
"Why is nobody berating China?" is my favorite oft-repeated refrain on HN.
They’re too busy berating the US.
CXMT sells the vast majority of their bits at the prevailing market rate, just like everyone else. They are adding capacity as quickly as they can, with a 5-10 year planning horizon, just like everyone else. It’s really not that deep!
https://www.tomshardware.com/pc-components/dram/memory-maker...
Yes of course their messaging to customers and the investment community is that they will be rational and measured in their investments. In reality, they are adding capacity as quickly as possible as margins are too high. However, capacity addition leading edge semiconductor manufacturing has a multi-year lead time.
> In reality, they are adding capacity as quickly as possible [...]
Even if we ignore the fact that you can't build out factories in secret, this would be securities fraud by publicly listed companies.
> ...as margins are too high
This is not the first RAM boom-bust cycle, and memory makers are an actual cartel convicted of coordinating in the past - none if them are going to break rank when they can invest the minimum and reap outsized benefits. Also, no one wants to invest in additional capacity when the bottom can fall out at anytime, and shareholders demand your head- not even the AI companies want to bear that risk, which is saying something.
PRC asked them to curtail DDR4 production so they didn't bottom out the market a year or two ago, and to focus on latest gen development, like HBM. They were the world leader in cost efficient DDR4 production at the time.
It's not really a blunder though. Given that total capacity is tightly constrained, Samsung and SK Hynix are happy to focus on what they do at their best and with the highest margins. Why shouldn't they supply the HBM market?
It's putting all eggs in one basket. If/when the higher-margin category collapses, they'll have no fallback. Imagine Chevrolet had discontinued Impalas and other low-margin cars, and switched to Corvettes during the pandemic
Even if there's a collapse in the high-margin market (I don't think anyone is expecting this right now), it will be slow and telegraphed in advance, giving them plenty of time to refocus on lower-margin products.
Good description of what actually happened. Do they even sell any conventional 2-door passenger cars besides the Corvette these days?
There is really nothing about the stock market that means only thinking about the mext few quarters. See all the losses on the profit and loss statements of AI tech giants, or, say, game console companies? Why are their stocks still valued so highly during these periods? The answer: investors are thinking long term.
It is really impossible to have quality long term thinking without capitalization accounting and similar instruments that come out of the "wester" system of business that chinese free enterprise gladly and speedily copied when it was made free.
I think the sentiment here is about management's tie of bonuses to near-term stock performance. Maybe not about the market itself, I agree with your view on investors want long term gains over short term fluctuations mostly.
> the average fixed contract price of PC DRAM DDR4 8Gb stood at $11.50
If that's the case, then why are the cheapest options I can find online multiple times that much?
That's a small b, that's gigabit. And that matches e.g. a "crucial pro udimm 64GB kit ddr4-3200 cl22-22-22 2Rx8" being at about 100$ a year ago.
Currently they sell here in Germany for 409€ each, that's 6.25€ for half of each of the 16Gbit chips on that kit.
> That's a small b, that's gigabit.
That explains it, thanks!
Because that’s just the price for the dies, still need packaging, integration and then retail distribution. Also raw BOM is like 1/5th of the retail price usually.
Raw BOM is much higher than 1/5th of retail price for ram. Some industries have higher margins than others.
11.5*8 = 92. I'm seeing plenty of DDR4 sticks below that price.
Brent crude is $71 a barrel, but you can't buy gas for $1.69. Why's that?
Are you able to buy crude by the gallon and refine it yourself? That would bring the cost down a bit.
You can buy oil on the market and take delivery, yes. Figuring out the logistics (tanker trucks, rail cars, storage tanks etc) will also be your problem though.
Commodities markets aren’t like eBay, nobody is just going to FedEx you a barrel of oil.
> nobody is just going to FedEx you a barrel of oil.
I'm sure someone will if you pay enough. But you certainly won't be getting the market standard bulk price.
Has DDR5 caught up to DDR4 latency yet? I remember it was worse at least in the beginning. There's more bandwidth per channel but a hw design can always add more channels for the desired BW. Not so for latency.
> add more channels
and unfortunately increase latency even more with registered DIMMs. Comparing bandwidth increase (50 GB/s) to the stagnated latency (~80..120 ns total, less than ~0.1 GB/s) over last decades, I'm wondering, whether one still can call today's RAM random memory (though sure it can be accessed randomly). Similar to hard disk drives. Up to 300 MB/s sequentially but only up to less than 1 MB/s 4KB random (read).
People have been wondering that for a while: https://news.ycombinator.com/item?id=19304281
I was wondering when people would find out about CXMT. I wish them luck and hope the US doesn't sabotage them. We need diversity and competition right now.
Awesome. Hopefully storage is next.
More competition is always good
This is just marketing. Why would you sell at 50% of market rate? Chinese production of NAND and DRAM is not significant, it's single digit %
It might be very effective marketing. The big non-Chinese OEMs trust and use Korean and Japanese DRAM, and they might have been unwilling to put DRAM from CXMT into their products. (CXMT is newish, does not have access to ASML gear, which ASML would like you to believe makes it harder to make high-quality DRAM, DRAM is historically not a very large fraction of the cost of most non-huge-memory machines, and a bad DIMM is an expensive mistake for a company like Dell or HPE that is on the hook for repairs.)
But now CXMT seems to have gotten at least Dell, HP (I wonder if the article meant HPE), Acer and Asus to buy and attempt to qualify samples. If CXMT lands some serious purchasing agreements while still selling well above cost, that’s a win for them.
Does the last part of your comment explain it? They need revenue to expand capacity and the market has opened up a window to become a bigger supplier while still being profitable.
> Why would you sell at 50% of market rate?
Because market rate is a 400%+ markup right now and not everyone is a greedy American kleptocrat with a diagnosable addiction to extracting every possible cent of wealth on the planet within a single fiscal quarter.
Is there a reason GPU's don't use insane "blocks" of sdcard slots (for massively parallel io) so the model weights don't need to pass through a limited PCI bus?
Yes. Let's do the math. The fastest sd cards can read at around 300 MB/s (https://havecamerawilltravel.com/fastest-sd-cards/). Modern GPUs use 16 lanes of PCIe gen 5, which is 16x32Gb/s = 512Gb/s = 64 GB/s. Meaning you'd need over 200 of the fastest SD cards. So what you're asking is: is there a reason GPUs don't use 200 SD cards? And I can't think of any way that would work
SD is obviously the wrong interface for this but "High Bandwidth Flash" (stacked flash akin to HBM) is in development for exactly this kind of problem. AMD actually made a GPU with onboard flash maybe a decade ago but I think it was a bit early. Today I would love to have a pool of 50GB/s storage attached to the GPU.
First gen HBF is targeting something like 1.2 TB/s!
Oh definitely. The AMD past product just stuck 4x m.2 slots onto the board. Today that approach would be 50-60 GB/s read speed which would be useful enough for something that any of the vendors could build with existing components.
One thing to note, those aren't the fastest SD cards, those are the fastest UHS-II SD cards. The future is SD Express and you can already get microSDs at 900 MB/s.
Some years ago I realized that if I had oodles of money to spend I would totally get someone to make a PCIe card with like several hundreds microSD cards on it.
You can buy vertical microSD connectors, so you can stack quite a lot of them on a PCIe card. Then a beefy FPGA to present it as a NVMe device to the host.
Goal total capacity, as you can put 1TB cards in there. And for teh lulz of course.
This isn't a very difficult thing to build, but I am curious - what's the point? Who is the market?
The main point would be teh lulz as mentioned, and the market would be me. You know, just because it's possible.
Physically easy to build, main challenge for me would be FPGA implementation.
The next gen inference chips will use High Bandwidth Flash (HBF) to store model weights.
These are made similarly to HBM but are lower power and much higher capacity. They can also be used for caching to reduce costs when processing long chat sessions.
Maybe latency. IIRC flash is a lot laggier than DRAMs and SRAMs.
The cure for high prices is high prices.
Still no confirmation if CXMT or YMTC actually removed from entity list, until then this is jus cheap domestic inputs.
As far as I understand, the "entity list" you are referring to is part of the "Export Administration Regulations", so it restricts sales from the US to restricted entities, not the other way around.
Great moment to break into the market if you're willing to forfeit profits
This is good news. The price you pay for jacking up your prices is losing market share.
Once established, the Chinese vendors will retain most the market share if the quality is ok. The SK/JP vendors are making a big mistake.
It's not clear that raising your prices to match the supply/demand curve is a mistake
They will compete on price if they are forced to, but they aren't forced to right now
It ain't the price raise that's the mistake (even if that's what's currently painful for those of us looking to buy RAM). It's the willingness to only raise prices, and not meaningfully expand production, that's the mistake.
Everyone is completely sold out and adding capacity as quickly as possible.
Are they really adding capacity?
Yes of course. Looking at the share prices of their suppliers— ASML, Lam Research, Applied Materials, etc.
But since when? There are public announcements about new energy deals since summer 2024. But I'm missing any information about similar RAM/NAND/HDD deals back then, so that corresponding shortages could be only for short time until, say, summer 2026.
I am sure you can lock great prices for ram for 2035 delivery.
If only on principle alone, could one secure a contract to buy a few TB of DDR5 memory to be delivered in 2035?
And if so, how?
Few TB probably not, but few EB I think you will be able to make a contract.
Oh well. Just wanted to do a commitment buy to at least say “I don’t care if my RDIMMs are long obsolete” for some existing DDR5 builds I have.
Good news. Now we need Chinese manufacturers of DDR4 chipsets and motherboards.
> Good news. Now we need Chinese manufacturers of DDR4 chipsets and motherboards.
Search aliexpress for X99 dual socket motherboards.
Chipsets don't determine the RAM type and all motherboards have been made in China for a while.
Taiwan dominates the global motherboard industry. (ASUS, Gigabyte, MSI, ASRock, etc. and MediaTek etc)
The big Taiwanese manufacturers are chasing the AI dragon.
https://www.digitimes.com/news/a20251021PD219/ai-server-asro... (Oct 2025)
OTOH, now I read small Taiwanese manufacturers who are left out of the Nvidia supply chain are reverting to DDR4 motherboards because of the DDR5 shortage. Strange times.
This decade is going to end with Chinese dominance in everything. Trump and AI handed them everything they need on a platter.
Western European countries got dominant, then got arrogant, letting the USA eat their lunch.
USA got dominant, got arrogant, letting China eat their lunch.
China is indeed getting dominant. They will get arrogant one day. Meanwhile, Western Europe and the USA are still very good places to live.
The pertinent question, then, is who's gonna eat China's lunch?
My guess would be south/southeast Asia (India and Vietnam seem especially promising), but if the US was smart it'd put its efforts fully toward as many infrastructure investments and trade agreements and immigration agreements as possible to create a pan-American economic union. We have the resources and technology to turn every country in North and South America into an industrial and technological powerhouse. We have the resources and technology to finally conquer the Darién Gap and connect North and South America with highways and high-speed rail. We have the resources and technology to go on the offense against drug cartels (while also eliminating the failed border controls and drug prohibitions that keep those cartels in business in the first place).
If we're gonna be imperialists, then by golly let's at least be productive about it.
China's big. It has a long way to go before all of it becomes developed enough that they have to worry about someone else eating their lunch.
And Latin American nations can't get started on economic development because their governance sucks. It's actually a decades-old problem, and not one that the U.S. can do much about. The one country that probably has the best shot right now is Argentina, let's see how they do.
> not one that the U.S. can do much about
Are you forgetting all those times the US sabotaged various south american governments?

China was dominant. They got arrogant before 1840, then there's 100 years of humiliation.
