Anecdata: Ordered my Mac mini M4 Pro (48GB) on April 1. Was told it wouldn't be available until June 4 but it just came in yesterday—a full month early. So I think there is an "underpromise; overdeliver" thing happening with current orders. Will be curious to see what happens with the Mini M5 release this year.
These don't have normal ram, right? The ram is part of the die of the processor? So... what's going on? They're keeping the chips for themselves? They're moving production to other lower memory configurations? But why? That's where demand is? Probably more demand at higher memory though?
I'd buy one or two but I can't stick them in a Colo because they don't have LOM or dual power supplies but I've been seriously thinking about buying one and just keeping it at home and having my Colo servers talking to it for local deepseek.
Not a high priority though considering how cheap deepseek is.
It seems like M3U 512GB RAM was a unicorn we won't ever see again :( Many skipped buying it with the hopes of a 768GB-1TB M5U but it looks increasingly unlikely.
A lot of discussion surrounding the ram shortage seems to imply that it will recover, but AI companies slurping up ram for training hasn't gone down and probably won't ever. Is there any signs that the situation is improving or is this just the new normal?
I hope it won't be this bad forever, but RAM companies are currently slow-walking any booms (not fast-tracking new fabs, etc.) in hopes of avoiding a bust. Seems it'll be more of a slow decay to still-inflated pricing.
The Mac Mini and Studio are due for an update in the coming months, a part of this is also probably that they’d rather save memory to build up their next gen model inventory rather than current gen ones?
Like trvz said, they use different memory. M3 Ultra uses LPDDR5X 6400 MT/s, M4 Max uses LPDDR5X 8533 MT/s, while all the M5 models use LPDDR5X 9600 MT/s.
The base mac mini I got has been one of the best tech purchases I've ever made, and of course as soon as I wanted another [loaded] machine for more serious work this happens.
It's absolutely wild that Apple's desktop machines now cap out at less ram than their portables which can't sustain an intensive workload without throttling!
People may not remember, it is ~1980 all over again. There was a massive 'chip' shortage back then were the mini-computer company I was at and many others could not get chips they needed.
In fact, chips were kept under lock and key to prevent theft. But there was a massive theft there were 20,000 chips were stolen.
Apple certainty has the financial resources to support other companies in e.g. developing specific innovations or building infrastructure (and has done so in the past) as long as there's an RoI for Apple.
It would surely be a smart move to support the right partner in quickly starting a new memory factory, precisely to Apple's specifications, in return for a long-term supply agreement? If Apple could secure their memory supply and at a lower cost than all of the their PC and phone competition, it would be hugely beneficial for them.
Memory designs are pretty entrenched with the various patents involved... I've said a few times that I don't know why Intel hasn't gotten back into DRAM production with their fabs. I suspect they may be contractually limited when they sold off their memory businesses.
Design is not the problem. Having foundry space to manufacture is the bottleneck. It is just all being sucked up (with AI needs being the big additional load).
And to be clear, the foundry space for CPUs/GPUs is not the same as for RAM, which is printed with much larger feature size in order to lower the costs.
For CPUs, they are still licensing ARMs cores, of course with their own modifications, and they bought Intel’s modem businesses, which likely gave them the patents they needed. GPUs I can’t speak to on this though.
Alas RAM is basically a commodity product, unless they could have some design advantage over others like the A and M series chips, there is little incentive to go into RAM.
If Apple had the manufacturing capabilities then sure, but they would still be running into the same resource constraints for inputs that everyone else is having nowadays.
At the moment, there are no solutions only responses.
Immune to shortages no. They're not suffering shortages because they don't have their own design, they suffer shortages because the whole supply chain has issues, starting from required minerals and going all the way to shipping.
And like the final product (commercial RAM) now goes to AI which pays better, processes/materials/factory utilization to make RAM would continue to go to another industry and not Apple, if that pays better then.

> But why?
So they don't have to stop producing machines entirely because they've run out of RAM chips. The problem they have is with supply not demand.
They don't use ram chips?
They do. They just solder them onto their SOCs (as part of the manufacturing process of the SOC). But they can't do that if they haven't got any.
It is still ram, not some magic thing
Still LPDDR

RAM has always been a boom/bust cycle - a square wave with the period about the time it takes to bring a new state of the art fab online (3 years ish)
I hope it won't be this bad forever, but RAM companies are currently slow-walking any booms (not fast-tracking new fabs, etc.) in hopes of avoiding a bust. Seems it'll be more of a slow decay to still-inflated pricing.

Does it free up fab space to make the newer ram?
No, the memory is different enough.
The listings on eBay are also super tight. If you can find a Mini/Studio it's priced at a premium.
I bought a Mac Studio with 128gb RAM and M4 Max a year ago for local LLMs. 96gb memory doesn’t seem to be sufficient?
What? 640K should be enough for anyone!

In early/mid 90-s, it was common for thieves to steal RAM sticks from computers in school/university labs.
Apple should just start making their own RAM and not rely so much on the suppliers like Hynix etc

Apple doesn't make their own CPUs, they just design them (using ARM IP). It's TSMC that makes them. The bottleneck with RAM is the manufacturing side.
They don’t use ARM IP. They have an architecture license. They basically created aarch64.
Memory designs are pretty entrenched with the various patents involved... I've said a few times that I don't know why Intel hasn't gotten back into DRAM production with their fabs. I suspect they may be contractually limited when they sold off their memory businesses.
>Memory designs are pretty entrenched with the various patents involved...
Can't be any more entrenched than CPUs, GPUs, and broadband chips, which Apple still designs.
Design is not the problem. Having foundry space to manufacture is the bottleneck. It is just all being sucked up (with AI needs being the big additional load).
And to be clear, the foundry space for CPUs/GPUs is not the same as for RAM, which is printed with much larger feature size in order to lower the costs.
I agree design is not the problem. I am answering the claim that "the various patents involved" would be the show stopper.
For CPUs, they are still licensing ARMs cores, of course with their own modifications, and they bought Intel’s modem businesses, which likely gave them the patents they needed. GPUs I can’t speak to on this though.
for gpus i believe they license ip from PowerVR/Imagination
Unless Apple comes up with a novel memory, which I wouldn’t put beyond Cupertino, it makes more sense to participate in economies of scale.
Apple normally just does prepayment for capacity- funding the capital for the production line they need
Alas RAM is basically a commodity product, unless they could have some design advantage over others like the A and M series chips, there is little incentive to go into RAM.
If Apple had the manufacturing capabilities then sure, but they would still be running into the same resource constraints for inputs that everyone else is having nowadays.
At the moment, there are no solutions only responses.
They could justify it as a capacity investment, like buying all the tooling for their aluminum laptop bodies.
It would take 5-10 years to design and verify a RAM design that comes anywhere close to the performance of modern day memory. Plus millions in NRE.
Why, is the idea that they would be starting from scratch, inventing it from first principles?
I would guess patents. If you don’t get the rights for an for an existing design, you need to build your own from the ground up
So if they start now, they'll be immune to shortages in 5-10 years.
It's a no brainer.
They'd have their own design in 5-10 years.
Immune to shortages no. They're not suffering shortages because they don't have their own design, they suffer shortages because the whole supply chain has issues, starting from required minerals and going all the way to shipping.
And like the final product (commercial RAM) now goes to AI which pays better, processes/materials/factory utilization to make RAM would continue to go to another industry and not Apple, if that pays better then.
