We now arrive at PP-512 = 328 t/s for LLaMA-3.1-8B on a Ryzen-5975WX CPU, up from 291 t/s when I last measured on 3c5f872. With FA and Q8_0 K-cache we get to 339.5 t/s.
We arrive at 302 t/s for LLaMA-3.1-8B on a Ryzen-5975WX CPU, up from 273 t/s.
After the changes I made to AVX2, it ends up being slightly faster compared to what I had for Zen4.

AVX2) and a Ryzen-7950X (Zen4)The improvement on
Zen4is very minor. The benefit there is bloat reduction as I'm now reusing the same implementation asAVX2.
