--- Comment #4 from Haochen Jiang <haochen.jiang at intel dot com> --- I checked the znver3 plot on the site, it seems that no regression occurs. Since znver4 enabled AVX512, that is the reason why I guessed previously. Could you also provide the option you ran with? I could not find where it hides in the site. Thx!
