I’m skeptical about this. Why would a faster processor in it of itself be more energy efficient at executing instructions?

- supertrope 3y agoA faster processor reduces execution time allowing the CPU to return to sleep status faster. Total energy used is power x time. While increasing operating frequency increases power quadratically due to P = CV^2, it is usually a net energy savings to let the frequency boost as high as a mass produced chip can go to minimize time spent in the highest power state. This assumes a finite bursty workload.
