Hey, when I was about to download the new version and looked at the different builds I remembered that I read somewhere that FX 6300s IPC performance of some AVX instructions in some scenarios is worse than some previous iterations in f.e. SSE4. And sure enough I found this here: https://stackoverflow.com/questions/60172943/why-using-avx-ymmm256-instructions-is-4-times-slower-than-xmmm128

Now, I'm not an expert or even amateur programmer, but do you know if the SSE4 builds are faster on an FX 6300?

I figure you had one, at least at some point: RobRich999/Chromium_Clang#26 (comment)

Sorry for stalking you about a decade old CPU.
