You forgot about PM uses less power than any other miner like lol or TR. So his loses in effectivity about some part of percent compensates by power economy in some percent!
This test was 2 part... Mainly was about how the console hash comes is pretty much always going to be 3.5% higher than at the pool.... There will be days where you actually get it (as you can see in my test, but odds are going to be very slim) Also, TRM produced a better over hashrate, over the course of the year, that .75-1% will add up quickly.
Power on both miners were so close that it was marginal.
I didn't know about your system, but for me PM uses about 1-2% less power only from sensors (overall power economy from wall can be more). So 0.75-1% less efficiency but 1-2% less power.
Until lol and TR didn't lower power draw by their miners for me choise is obvious.
Software power draw means 0.... I have a 5700xt that's showing software power draw at 77w and 80w!!!!!!
By the way; the software power draw for PM on these cards (with these settings) showed 84w.
