I don't know what the belly-aching is for. This is a pretty fair comparison of low power M2 iGPU / APU vs what is probably the best low power iGPU / APU in the x86 world.
Apple pretty much rules this very low power space in performance. They have the best
LOW POWER laptop CPU and iGPU.
The issue is that if you need more performance in the Apple ecosystem, you really can't get much more. There's no equivalent right now for a competitor to say the 5900X or 12700K, much less the 5950X or 12900K.
There also isn't any good competitor to the 12900H or 6900H.
Take a look at what happens when you put the M2 in perspective against other recent laptop chips - not restricted by 25W max power.
I mean, a 1280P - which is a 28W median chip allowed to go to 64W on turbo - is 13% faster. The 45W 12800H is 31% faster. The top line 12900HX is 84% faster.
Apple does not have anything that competes with these, so if you need anything faster than the M2 you are SoL in the Apple space.
