> You might argue that 8 RISC instructions are not comparable with 8 CISC instructions, but even with say 4 CISC instructions it will still consume more energy
Alder Lake decodes six. And again, your intuition about power costs here is just simply wrong. Instruction decode is Simply Not a major part of the power budget of a modern x86 CPU. It's not.
