That's certainly overclocked or very high PBO offsets, at stock the 5800x gets around 1700-1800 ST.

But if you run TWO single-threaded workloads at once, the clocks dial WAY back. Meanwhile, the M1 can keep all cores at 3.2GHz pretty much indefinitely.

Yeah, that looks correct. With faster ram and PBO it should hit closer to 1800.

Here is my 5600x with PBO enabled and 3800MT/s CL16 DDR4 https://browser.geekbench.com/v5/cpu/10516280

5800x would have a max clock of 4950mhz with PBO
