Power efficiency AFAIK.
I see. Well they're two entirely different architectures so that's not really going to happen. ARM will likely always use less power without some heavy investment in wizardry for the x64 architecture because of the design.
It's not new however. Back in the 90s my dad used to say RISC (MIPS/arm) was going to trounce CISC (x86) due to the inbuilt efficiency of the architecture but there are many other factors that determine market winners.
because apple controls both OS and hardware to minmax power efficiency. you run the same hardware with asahi linux, efficiency isnt as good.
same idea with pc handhelds. the reason why the steam deck has reasonable battery life for its battery size is because valve has full control of steam os CPU governor to tweak. AMD and Intel do not for Windows.
the main thing arm has that the x86 chips dont have is a functional sleep levels that arent picky.
the OS matters a lot more than the hardware does than people think it does.
you see this often with hardware companies and their brand of android.
