I understand that Apple controls much more its ecosystem than either AMD or Intel, but I cannot imagine a M1/2/3 being less "generic" than an AMD/Intel, care to elaborate?

Also, the question is what makes the architecture more power hungry. Originally there was this disctinction of CISC (intel/amd) vs RISC (arm/apple) but my understanding is that at least intel/amd have some cisc runnning on risc architecture, meaning, externally it looks like a cisc/x64, but internally is a risc or riscish.
