Seems relevant to your problem:

Arch Linux on the Framework Laptop 13

@dosssman Thanks for reply! My friend’s issue is resolved by using intel_pstate scaling driver instead of intel_cpufreq (the driver used given intel_pstate=no_hwp option). The scaling driver without hwp seems too aggressive for 12th gen, limiting most of its cores to 400MHz. Even power state of intel_pstate won’t have that issue.
