Ile widzisz rdzeni w htop? Ten procesor ma 4 rdzenie 4 watki. Ale masz "SMT disabled"
w Mds mitigation.
Jesli tak to chyba 1 rdzen tylko masz dostepny?

U mnie tak:

lscpu
Model name: AMD Ryzen 7 5800X 8-Core Processor

Spec store bypass: Mitigation; Speculative Store Bypass disabled via prctl and
seccomp
Spectre v1: Mitigation; usercopy/swapgs barriers and __user pointer
sanitization
Spectre v2: Mitigation; Full AMD retpoline, IBPB conditional, IBRS_FW, STIBP
always-on, RSB filling
