> good luck parsing through 100 different "performance optimization manuals" from 100 different companies.

Imo this is pretty misguided. If you're writing above assembly level, you can read the performance optimization manual for Intel, and that code will also be really fast on AMD (or even apple/graviton). At the assembly level, compilers need to know a little bit more, but mostly those are small details and if they get roughly the right metrics, the code they produce is pretty good.
