Just AVX2 test #116
Comments
Thanks! So avx2 move generation doesn't seem to beat regular magic move generation on Zen, and compiling specifically for Zen does seem to help a bit (with -march=znver1 seemingly outperforming -march=znver2). |
That AVX2 move generation is doing well in pure NNUE mode is very interesting. I should look into this to try to understand why. That BMI2_FANCY does poorly on Ryzen is not so strange, as it uses the pdep/pext instructions even more. |
