My 8700k has lower then average single core performance related to other non-oc 8700k bench results, while multicore is OK. I've noticed frequency never rises above 4.3 ghz, I never see promised turbo boost 4.7ghz. Mobo: asus z370-f gaming.
Looks like turbo boost isn't working properly. Any suggestions?
my 8700k results:
average non-overclocked 8700k single core bench:
cpu-z bench:
bios:
Ok, problem solved, now my 8700k performs on par with cpu.userbenchmark results. The reason was, for some reason, the motherboard bios (asus z370-f gaming) had CPU C-states as disabled, which didn't let the CPU boost to more then 4.3Ghz.
After enabling, CPU boosts to 4.6Ghz (though I never got advertised 4.7Ghz) it puts it's benchmark results on par with other non-overclocked results.
Regarding CPU-Z results, it looks like those are outdated, before Spectre / Meltdown patches, as on forums and reviews 550 is not an average for non-OC single clock CPU, it's closer to 500.
