An interesting implication of this is that AI inference and training has a path to a ~3x hardware cost reduction (and maybe ~2x total cost reduction) without any technical innovation whatsoever, we just need to wait for dram supply to meet demand (either by manufacturing scaling or just waiting for the current rate of manufacturing to fill the demand spike).

What’s the lifespan/refurbishability of the capex elements like the “GPU” modules or even the DRAM soldered into them?

Why did this happen so suddenly? Why were tech savy investors unable to figure this out when the datacenter craze had already started? How to explain this lag between quickly rising demand for all datacenter components besides memory?

Nine years after Google's seminal paper lit the fuse on AI, a total lack of manufacturing foresight has trapped over a trillion dollars of incoming capital in a hardware bottleneck. The entire sector is now facing a critical RAM starvation crisis where memory manufacturers are actively slow-rolling supply just to keep prices high and avoid running out entirely. This has created an unprecedented supply-and-demand dist…

"That leaves small SAAS companies exposed to incoming inflation in the cost of hosting".

Which they will pass on to their customers. If their product provides enough value the customers will pay.....

I wonder why the hyperscalers aren't vertically integrating more and building their own fabs. Sure, a fab costs a billion dollars, but they're currently spending hundreds of billions of dollars purchasing chips from NVidia and others.

I'm not sure if they should vertically integrate, it would probably be a better idea to directly fund the expansion of capacity, much like Apple does when they scale up a new technology for iPhones. However, that the hyperscalers and AI companies aren't doing this says a lot about their true beliefs about how much future demand AI will have. AI companies claim they will need a ton of massive expansion, but are unwill…

Oracle is getting sold because of how much capex they're spending on new data centers in the middle of a high rates environment. It's not like they're stockpiling cash due to doubting AI.

Earlier quoted context omitted.

I mean the biggest risk is Chinese CXML benefits and capturing markets that others are leaving hanging and then being able to compete and push out the others when costs start to normalize. As for 20-25% growth not being enough, I think it's not that far off, if we assume data center build out plans hit a wall and slow down significantly, and the AI heat starts to cool off. I don't think 20-25% may be enough in the sh…

Is there any indication research is being focused on reducing menory footprint of inference for frontier class models? Is the low hanging fruit already gone there?

If they manage to make memory more efficient, they’ll just increase the context size and/or model size.

We just haven’t reached the diminishing return of gen AI capabilities yet.

Models will get more useful if you have higher context size or higher param size. Then people will just use the models even more, leading to even more memory demand.

It seems to me the max memory you can buy in a laptop stagnated for the past 3 years or so.

My several years old laptop has 128GB of RAM, is that not enough? I admit that it's a pretty heavy one.

Ah, the old decrucialisestablishmentarianism .

I found the phrasing weird myself, I quoted wikipedia

Everything I read seems to suggest that RAM capacity is going to grow at 20-25% a year, which just doesn't seem good enough. Even in consumer use cases, phones and laptops would benefit greatly by double the amount of RAM. And then obviously, the AI need is gigantic. I don't see it going away. I mean, it may not grow as fast as now, but I don't see it growing away either. I get why the memory makers do not want to ba…

Looking at the history of the memory industry the biggest risk is that a firm would over produce and go bankrupt. Maybe this time is different but so far no memory chip maker has gone under because their competition increased capacity.

Low hanging? how low hanging are we talking, the basic stuff is gone. Largely big challenges around quantization were solved 2 years ago, and we have just been improving from there.

But can massive gains still be made? Definitely.

The entire AI hype is based on the paper Attention is all you need, and Attention is basically loading a huge matrix of all the tokens in memory, how well you can optimize this attention layer is basically how most architectures are trying to solve for performance and memory usage.

Only one with significant gains in it is DeepSeek (or so I would like to believe because others don't make their work open for folks like me not in Big AI Labs to read). Their MLA architecture reduced KV-cache memory requirements by upto 90%, ofc that's purely architectural change.

With some quantization like Turboquant from google you could push it down to ~1/3 of that. So 96% memory savings when talking about kv-cache.

But the models are close to being saturated for quantization based memory optimizations. We will have to see some architectural changes for a significant shift now.

In theory the new futures markets for chip components would help here, since it would allow DRAM suppliers to insulate themselves from that risk.
