This calculation makes me curious, as I know very little about computer engineering/hardware but want to learn: what is the current-most energy-efficient general CPU architecture/core in performance-per-watt? Some high-speed ARM? A Y-series x86?

This may not have the latest record, but lots of interesting and relevant info here: https://en.m.wikipedia.org/wiki/Performance_per_watt
