Sorry, I dropped a few words accidentally before submitting and it’s too late to edit it :-( my bad.
I meant to ask for benchmarks across the power spectrum (measured by actual pull not OEM TDP) and off charger. That’s where the x86 processors down clock heavily to keep power in check, and M series pulls ahead because it doesn’t follow suite.
The M series, even at launch, weren’t the king of outright perf, but they were for power to perf.
The M series at launch was already on TSMC 5nm when nothing else was yet.
The problem with asking for benchmarks that actually measure power draw is that somebody would have had to have done them, which hardly anybody does, and specifically on the few CPU models that were made on the same process. So if that's what you want to see, where are yours? Find a comparison that actually measures power draw between two CPUs with similar performance/TDP on the same process, like the M1 Ultra and the Ryzen 7945HX3D.

That's not really how either of them work. CPUs from any vendor will run at lower clocks under threaded workloads in order to meet their power budget. This is also why the high core count CPUs actually have the best performance per watt -- the cores are clocked lower which is more efficient but you still get the performance from having more of them. And then "race to sleep" etc.
