The memory makers will not expand demand drastically. It is in the nature of their business to keep the market under-supplied, otherwise the following oversupply will kill them. Instead, supply is just rerouted from less profitable segments such as mobile and personal computing.

Supply and demand always balance out. There is no way manufacturers aren’t going to compete away these inflated margins, as long as they feel like this demand is sustainable.

There's very few manufacturers, I believe 3 globally? And there's a large moat. Nobody can compete with them in the next 10 years. It's really not hard to coordinate action between 3 companies.

Possibly the best deal there is I really need to shut up, or bite the bullet and by one. If you graph the tokens per second on the 5090, your jaw will hit the floor at how cheap it is

With only 32gb of vram, you can only run small/quantized models, in which case what's the point? At $4000, that gets you 20 months of 10x claude or chagpt subscriptions, which provide far better models. You'd need some use case where you can tolerate worse models, and use a steady supply of them. That doesn't match most people's usage patterns.

If you can do what you need with qwen3.6-27b, it starts to look really interesting. That model is crazy good for the size, but it's a pain tweaking the params to run it on a 4090 with decent context and decent token speed. A 5090 looks tasty from that point of view, and only more so if you think in terms of the probability of that model being roflstomped by something in the same weight class in the next couple of years. I reckon that probability is significantly non-zero, but fundamentally it's a guess.

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).

China is about to flood the market and prove this notion wrong. If there is demand they want to meet it with supply.

But to your point, that is exactly how American companies like to play now. No one is stopping them from screwing over the consumer.

I have a Micron near me and they are building another chip facility but we are years away still so I suspect China will beat them to the punch.

This is 100% going to kill the home built pc market. When I started building gaming pcs, the top top card was 750$ (NZD). Now they’re 10,000 just for the gpu and another 1-2000 for ram. People used to get into gaming pcs as an affordable hobby, now it’s making general aviation look like plan B.

Don’t you worry - Microsoft and Amazon will have you covered with cloud streaming. Can’t afford a computer because they bought up all the supply? They’ll conveniently sell it back to you with a subscription! You’ll own nothing and be happy.

Awful time for gamers and PC hobbyists not fully into AI.

there's much more than triple A video-games running at 240 Hz on Ultra settings... a 200 USD laptop/computer has enough power to run hundreds of interesting indie games and AAA from the past

It's still unclear to me: the shortage is semiconductor boules / wafers? or the shortage is semiconductor fab process step availability? As long as the discussion seems focused on memory, I'd suspect the latter, but if its really the semiconductor boules/wafers, then I'd expect the boule growers to profit, not the memory makers, who just pass on the cost. So which is it?

This covers it pretty well https://news.ycombinator.com/item?id=48229319, TLDR -memory for AI uses more wafers from same production line as other memory and is more profitable, building new fab very risky historically for companies. The companies have cut production of other memory to favor memory for AI and the market for memory for AI is still unfulfilled so prices still go up for customers of every type.

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.

A fab costs a billion dollars (really a lot more) and 5 years. It doesn't do anything for anyone today.

It sure looks like Sam Altman's masterful gambit to corner the memory market has had unforeseen consequences.

Is any of this actually unforeseen? Buying the vast majority of the world’s supply of something does have mostly predictable consequences.

Regardless of the specific mechanics of the bottleneck, we know what the proximate source of the problem is: openai locking up 40% of Samsung and SK Hynix wafer capacity for the next few years. That's what triggered the madness.

You know there's other strategies? Companies can be more clever than naively undercutting each other...

Memory in particular ... https://en.wikipedia.org/wiki/DRAM_price_fixing_scandal

The entry-cost to getting into memory is on the order of $billions and years - you can do just about anything...
