The main power advantage of the apple chips is when the system is mostly idle - under mid to high load power to watt has been comparable for a few years already (at least AMD and Apple, intel was way behind - but I guess they caught up recently). The main reason behind my M3 MBP back then wasn't so much power efficiency - but that I can get it with 96GB of RAM. It's nice that I can go a full office day without charging - the previous x86 notebook couldn't, but a decent one from the M3 generation probably could as well. But also if I put proper load an that thing the Macbook battery is done in less than 2 hours.
