Apple Silicon cores have set of target frequencies and switch between them very quickly. You can see it in `powermetrics` output:
Also there are some hidden details within this chips:
You checked something wrong. Apple mobile CPUs have even more flexible frequency scheduling...
But this Threadripper 3990X has similar energy-efficiency only at 70% per-core performance of M1 Max.
Apple M1 in Macbook Air loses about 20% with the throttling from 15W to 7W, so I would expect M1 Max to be 2-3x more efficient than Threadripper at the same per-core performance.
I'm not saying it should be used for benchmarks. Just pointing out that there are real use-cases for running "generic" ARMv8 binaries.
Main reason for using docker is to have *exactly* the same environment on server and on developer machine.
And no one in their right mind would recompile Ubuntu...
I think 3.0 GHz is maximum when multiple cores under load. It can reach 3.2 GHz only in singlecore.
And 15W is only from CPU cores without DRAM, GPU, regulators etc.
I belive, it's A12Z score from DTK, not M1: https://forums.macrumors.com/threads/cinebench-r23-with-support-for-apple-m1-soc-is-now-out-geekbench-scores-up-too.2267129/
