"E cores running low QoS threads at close to minimum frequency take about four times as long, 38.5 seconds, but use less than 45 mW power per thread. Total energy used to complete one thread is therefore over 23 J when run on P cores, and less than 1.7 J when run on E cores. E cores therefore use only 7% of the energy that P cores do performing the same task.”
