Zen4 is competitive when it comes to actual computing. When doing (almost) nothing, the Apple system comes out on top, but that also has a lot to do with its software.

Yeah, Apple have been massively optimizing for heterogenous cores and having efficient power states when not doing any work.

I think macOS is also just better at actually being idle when the user isn’t doing anything. Windows seemingly always has something shuffling around in the background.

This is definitely part of it, as anyone who’s run Linux and Windows on the same machine can probably attest Windows is constantly doing… something? It is quite odd as it doesn’t seem to offer much in exchange for all these wasted cycles.

Source for this?
Geekbench and SPEC heavily favors Apple Silicon in both raw performance and perf/watt. The perf per watt is 2-3x.
The only CPU benchmark Zen4 wins in is Cinebench R23, which uses Intel Embree engine inside and heavily optimizes for x86 AVX instructions.
M2 is on TSMC N5. AMD's Zen 4 mobile processors are made with TSMC N4. From die shots, I believe the P-cores in the M2 are about the same size as Zen 4 cores. And yet Apple's M2 laptops are a good deal more power efficient than Zen 4 laptops.
