Apple their benefits are that they hide a lot of their performance under their ( oa media ) encoding engine for a lot of tasks. When the CPU is put pure on CPU tasks, that famous power efficiency scales very close. Notice how a 6nm vs 5nm are pulling very close the same power in MT tasks.
Apple gains are mostly in the ST tasks where its reporting better performance on single core tasks. We see 4W * 4 + Efficiency cores (21W) result in 9581 in MT. But why can AMD deliver 10468 on a 25W power budget because X86 when not turbo boosted to hell, is actually very efficient.

Its been clear for YEARS that AMD and Intel have been turbo boosting their CPU way too much for ST tasks. So why is AMD so efficient in MT tasks? Because CPU are not designed for laptop first, or desktop first. Its server first. Where you want great MT performance at the best possible power usage ( most server CPUs that use the exact same cores are sold with very conservative clock speeds for that reason ).
Then those CPUs get filtered down to desktop, where they need to show great benchmark/gaming results, so there goes the clock speed up because that is the most easy way to reuse the same design. That CPU then needs to conform to laptops and well, your just trying to shoehorn server / desktop designed CPUs into laptops. And that becomes harder and harder but when you really analyse the result on a more equal playing field, ARM is not that special.
We already see how Smartphone are becoming hotboxes because of that same drive for more performance at any cost, despite it also being ARM technology.
