The single thread performance for modern high performance CPUs are all very close to each other. Apple's latest usually has a small advantage because they're the first to use TSMC's latest nodes, which is good for something like 15-20%.
The fastest multicore CPUs are the ones with a lot of cores, e.g. 64+ core Threadrippers. These have approximately the same single-core performance as everything else from the same generation because single-core performance isn't affected much by number of cores or TDP, and they use the same cores.

Everyone also uses Geekbench to compare things to Apple CPUs but the latest Geekbench multi-core is trash: https://dev.to/dkechag/how-geekbench-6-multicore-is-broken-b...
