What benchmark do you have that says a R9 7950X "consumes as much and at times less power than an M1/M2"??? I mean, a) of course that's a crazy comparison because the M1/M2 is an entry-level laptop chip and the 7950x is AMD's flagship high performance desktop chip and b) the M1/M2's power consumption at full load is ~20W and the 7950x idles at 20-30W.
A reasonable comparable is one of AMD's monolithic laptop chips like the 7840U or (if you're willing to consume more power) 7840HS.
