A quick&dirty power draw / performance comparison

Just for fun, nothing scientific.

Rock PI S has the best performances per watt. Bravo!

No cooler is the winner :smiley:

@jack , isn’t the memory speed @ 8KB a bit low (a problem also on Rock64, TBH)?
Maybe the initialization code for the CPU L1/L2 Cache could be tweaked a bit?
And: is RAM clock already “tuned”, or we can adjust it with some boot parameter?
