AMD processors have so far been immune to all but one attack and in the previous gen processor the mitigation caused a 2% performance hit. This gen has specific hardware for mitigating these side channel effects so the numbers you're seeing are with the mitigations.

I think the parent comment is asking if the patches have been applied to both chips in the benchmark. Yes, AMD perf will be largely the same but comparison between patched and unpatched will be different.

Not sure about this benchmark, but the differences in the AMD presentations have been Intel unpatched comparisons.

Zen2 has hardware mitigations so "the same".

I should have said, compared to Intel with mitigation on...
