i9-10900K / 128GB 3600MHZ / Asus Z490 ProArt / 5700XT Nitro+ / Big Sur
No Overclocks
To be clear: I have almost identical configuration and your scores are mosdef "overclock". Those are 5Ghz scores.
The trick is that Intel and board makers designed the i9-10900K to be overclocked by default. There's no headroom that's all you can get without doing something ridiculously exotic on cooling. Your system is pumping at least 250W CPU dissipation multicore on a practical workload, so it's a space heater.
Also note the negligible 3 percent gain with the ASUS Multicore Enhance. Irrelevant feature except for gamer bragging rights.
Intel 12th gen crushes the 10th, but too bad about no iGPU for hackintosh because that little sucker not only pays its own way but tips huge based on cost in die area and power for practical Mac applications.
Something I think that's under considered is that a beefy AMD eGPU usually has a separate media xcoder ASIC which may get confused with the display rendering capability. This can make up for missing iGPU iff the App can get at it. Plus there are performance distinctions between "gamer" and "workstation" GPUs. Apps on Mac that make good use of eGPU have to be carefully tailored while the industry is herd of cats, and most PC eGPUs are designed for games. It's complex.
The dialog on these forums could do better at helping each other appreciate the finer points.
This last point is especially pertinent to Apple's Mac product evolution, because all signs point to Apple being able to capitalize on its vertical architecture integration in a way that puts hackintosh into sunset. Look around and you see PC industry struggling to adapt to Apple ways, which is a tremendous reversal in industry of last 20 years.
