Surely it cant be due to be AI performance?

The 7900xt is 103 tlops of fp16, 7900xtx is 122.

the 4070 is at 117 of fp16 (234 using sparsity) on a smaller chip and thats not banned.

The only thing 7900XTX/ W7900 beat the 4090 in is RAW video debayering in DaVinci Resolve that I'm aware of

7900xtx matches 4090 in Stable Diffusion as well. And I think it's also quite competitive in LLMs. Since LLMs are memory capacity and bandwidth bound, and 7900xtx and 4090 are close there.

The 7900XTX beats a 4090 in Topaz AI, at least in benchmarks
