Changing the balanced_performance EPP has better performance/watt compared to default powerup EPP value of 128. Changing the performance EPP to 0x10 shows reduced power for similar performance as EPP 0. On small form factor devices this is beneficial as lower power results in lower CPU and skin temperature. This results in reduced thermal throttling and higher performance. Signed-off-by: Srinivas Pandruvada Signed-off-by: Rafael J.
