All the benchmarks put the equivalent Nvidia cards almost 2x more in Stable Diffusion https://www.tomshardware.com/pc-components/gpus/stable-diffusion-benchmarks

I hope that is an old benchmark and times have changed, but I can’t find anything like it that is more recent.

For a bit of my soul I get a lot more ai power.

AI works on AMD but the speed doesn’t seem to be anywhere near Nvidia.
