I'm curious if such great perf/watt is something that arm architecture is allowing or the same is possible in x86? if that's because of risc instruction set does it mean that riscv could achieve something similar in the future?
- TylerE 3y agoI don’t think it’s risc-the-philosophy per se, but a difference of priority. X86 historically prioritized clock speed (ultimately culminating in the utter dead end that was Pentium 4). Then Intel back tracked to The Core/iN/M series, which actually reverted to essentially an updated Pentium 3 design, and has focused on raw power, power draw, heat, and cost be damned. ARM, in the other hand focused on power-per-watt from day 1. My M1 studio, fully wide open, draws less than a quarter of what my old i7/3080 beat did at idle.
