Zen3 architecture CPU, core computing power is unbalanced

[3600cpuminer]

My zen3 architecture CPU, whether it is a notebook (5800u es) or a desktop (5950x), the hash is unbalanced, and core 1 is always lower than core 0. This has never happened with other architecture CPUs, such as 3950x, 7742, and 7900x. The computing power of core 1 is significantly lower than that of core 0. The exact same system is used. I have tested multiple versions of xmrig and it is the same

I ran the benchmark directly and it was still the same. Core 1 was significantly lower than core 0.

I had the similar issue on my 7950X. I don't remember exactly what I did to fix it, but it was because of my Windows installation. I think I installed some "gaming optimized" build that turned off Spectre/Meltdown mitigations, and it resulted in this unstable hashrate. I fixed it by re-enabling those mitigations in the registry, but I don't remember how and I can't find the instructions now. Stock Windows 10 doesn't have this problem, but it needs tweaks to be done manually: https://www.reddit.com/r/MoneroMining/comments/f18825/windows_10_tuning_guide_for_randomx_mining/
