Here are the efficiency testing results for two more computers. I pulled the 3200G out of the Deskmini A300 and installed an A8-9600 that I already had in it's place. The 3200G is now on a ASRock B450-HDV R4.0 so it will get re-tested for efficency in the future.

Celeron J4105 - This computer did not respond well to adjusting the CPU frequency so I found a different way to increase the efficiency.

A8-9600 - This is not an efficient processor. I knew older AMD CPUs were not that good but I did not expect it to be this bad. The response to lowering the CPU frequency was similar to the 3200G so it is probably the motherboard that does not like the operating system to adjust the CPU frequency.

Total power reduction so far:
i3-9100 - 85W to 46W = 39W savings
GTX-1650 S - 145W to 79W = 66W savings
i5-8250U - 30.5W to 30.5W = 0W savings
3200G - 75W to 36W = 39W savings
J4105 - 20W to 21.4W = -1.4W savings
A8-9600 - 70W to 36W = 34W savings

See the attached pictures for details. In the pictures I am tracking a lot more than just power use changes.
