What stands out about these tests to me, apart from Apple Silicon remaining highly impressive, is that AMD in both and Intel at least in multicore are beating the Snapdragon on performance per watt. Many people boil Apple’s efficiency down to an ARM vs x86 thing, but that’s a tiny part of the chip by now, it’s more in Apple’s bespoke architecture around it.

Here we see AMD even on x86 beating an ARM chip on Perf/watt, Intel on multicore, and Meteor Lake launching within a month will drop power use by 50%. It’s not just or even mostly the ISA, it’s everything else around it that matters more.
