The CentOS ISA special interest group (SIG) has been evaluating the performance of CentOS Stream in the event its x86_64 baseline were to be raised from x86-64-v2 to x86-64-v3. Currently CentOS Stream 9 targets x86-64-v2 but in upping the support requirements to x86-64-v3, it would allow the ability to engage AVX/AVX2 by default and make use of other newer instruction set features. The x86-64-v3 baseline roughly correlates to Intel / AMD CPUs from 2015 and newer...

Back in April AMD Linux engineers posted enabling a new CPU feature called Dynamic Boost Control to be found with some unspecified Ryzen SoCs for tuning the processor cores for optimal performance.
