I mean it kind of is considering that's comparable to a 5070 which has 672 GB/s? Benefit of NVIDIA being the only one using GDDR7 for now I guess.
I don't have an Intel dGPU, but I suspect the situation there is even worse. I mean you go to the torch homepage: https://pytorch.org/get-started/locally/ and Intel isn't even mentioned. (It's here though: https://docs.pytorch.org/docs/stable/notes/get_start_xpu.htm...)
