Exploring x86-64-v3 for Red Hat Enterprise Linux 10 | Red Hat Developer
RHEL 10, we are exploring whether we can go a step further, to the x86-64-v3 level.
(略)
The x86-64-v3 level has been implemented first in Intel’s Haswell CPU generation (2013). AMD implemented x86-64-v3 support with the Excavator microarchitecture (2015). Intel’s Atom product line added x86-64-v3 support with the Gracemont microarchitecture (2021), but Intel has continued to release Atom CPUs without AVX support after that (Parker Ridge in 2022, and an Elkhart Lake variant in 2023).
