AMD GPUs aren't very attractive to ML folks because they don't outshine Nvidia in any single aspect. Blasting lots of RAM onto a GPU would make it attractive immediately with lots of attention from devs occupied with more interesting things.
does the 7900xt outperform the 3090ti? if so, there's already a market because those are the same price. I don't mean in theory are there any workloads that the 7900xt can do better? Even if they're practically equal performance you get a warranty and support with your new 7900xt.
Problem with MI300x is the price. Problem with 7900XTX is that it's at best as good as Nvidia with the same RAM for a similar price. If 7900XTX had e.g. 64GB of RAM, was 2x slower than 4080, and kept its price, it would sell like crazy.
I have a 7900 XTX. Honestly I regret it. It took two years for the driver to stop randomly crashing with very pedestrian ROCm loads. And there's no future in AMD support now they're getting out of the high-end dual-use GPU game anyways. I should have gone with NVidia.
