See also: > In 2020, through a collaboration between AMD, Intel, Red Hat, and SUSE, three microarchitecture levels (or feature levels) on top of the x86-64 baseline were defined: x86-64-v2, x86-64-v3, and x86-64-v4.[41][42] These levels define specific features that can be targeted by programmers to provide compile-time optimizations. The features exposed by each level are as follows:[43] * https://en.wikipedia.org/wiki/X86-64#Microarchitecture_levels https://en.wikipedia.org/wiki/X86-64#Microarchitecture_level...
