  That thing is intel-only, or at least Linux kernel thinks so: https://github.com/torvalds/linux/blob/master/arch/x86/kernel/tsc.c https://github.com/torvalds/linux/blob/master/arch/x86/kerne... And even on Intel, TSC is not reliable: https://lwn.net/Articles/388286/ https://lwn.net/Articles/388286/

    AMD CPUs have supported constant_tsc and nonstop_tsc since the Phenom era too.

    That lkml thread was back in 2010, before invariant TSC was a thing.
