Aren't these specs already outdated? Seems meh. I would think players would like to bring something new to the table instead of bringing what was okay two years ago or so.
Give me 1TB RAM and 5TB/s or something that exciting.

5 year old GPUs are still at crazy prices.
Plenty of businesses want in local inference and are priced out.

You can't do quality inference on such a toy. It's a myth.

What exactly do you propose they do? Do you think they are holding back supply? Should they sell at less than market price? That's just handing the profits to scalpers/middle men.
I'm sure NVIDIA, AMD, Intel, Qualcomm, etc. would sell more hardware if they could, but they can't.

They have no reason to sell more if they can gouge the existing supply

This is all the CPU companies playing catch up with Nvidia and AMD.
The thing you are describing is much closer to AMD and Nvidia latest generation server offerings.
See MI455X for the absolute cutting edge and MI350P for something you can use outside of a datacenter.

8 of those cards give you 1TB of ram and 4.4TB/s

It may be a semantic thing but I don't think bandwidth pooling works like that? Unless your blocks are distributed perfectly between cards there's going to be data passed between each card and from VRAM to compute. Correct me if I'm wrong though
[–] msandford 3 days ago
I think the way it works is that the weights have to get streamed through the compute and the weights can be split very easily. With multiple cards you do have a coordination/communication phase after each layer of weights but that's usually much less significant than the compute phase.
[–] throwawayffffas 3 days ago
It depends on how you slice the weights. You can split along layers which means each GPU waits for the previous one to finish or you can split the tensors across gpus.
Splitting the tensors is closer to n times the effective vram bandwidth but there are still overhead, sync waits, and reduce steps that eat away at the overall performance.

But this gives you significantly more memory capacity for a compute/vram bandwidth tradeoff (i.e. arithmetic intensity) that's ultimately comparable to Blackwell, perhaps even more skewed towards compute. This seems good if you care about being able to store larger sparse models and more KV caches because that ultimately bottlenecks your ability to do inference.
