To add a tiny bit of technical detail here, vanilla Arch enforces support for x86_64 v1, meaning all software available in the Arch repos is built to not use any cpu feature that didn’t exist in v1. Not a bad thing since it allows for support of older (64 bit) hardware, but it does leave like 20 years of microarchitecture advancement on the table.
According to the CachyOS website, they have repos with software built for v3 and v4 which can apparently juice your rig for an extra 20% performance.
