I've been diving into the performance differences between CPUs like the Zen 2 and Intel's 10th generation. I've seen various opinions on specific comparisons, such as the 10600K vs. the 3600XT and the 10700K vs. the 3800XT. It seems that while Skylake CPUs have strong gaming performance, Zen 2 might lag behind due to issues like cross-CCX communication and memory access latency, even if its IPC is slightly better, supposedly around 5%.
I'm curious to know: for CPUs with equal cores and threads, like the 3800X and the 10700KF, how much higher or lower should the frequency of Zen 2 be to reach similar gaming performance as Skylake?

It's a bit more complicated than just clock speed. Factors like architecture, cache sizes, and latencies play a big role too, not just how fast they're running.
There's no straightforward formula for this. You'd need to select specific gaming scenarios and perform tests to see how they stack up against each other.
Got it! That makes sense, I'll check the benchmarks.
If we assume Zen 2 is running with 3600 C16 memory, and Skylake is using optimal memory settings, you can still see differences in gaming performance. For example, in demanding games like Hitman 3 or RDR2, the overall architecture impact is significant. Using boards like X570 or Z590 will also make a difference.
Historically, Ryzen CPUs didn't catch up with Intel in gaming until the 5000 series and Intel's 12th gen. For example, the 3600 was only slightly better than the 8700K. Check out benchmarks on sites like Gamers Nexus or Hardware Unboxed for accurate comparisons.
Thanks for the recommendation, I’ll definitely take a look!
That’s a good point! I’ll keep those in mind while researching.
