Power Consumption
Since power consumption is a big deal these days, we ran some simple power consumption tests on our test beds. The systems ran with the power supplies, case fans, video cards and hard drives. To measure idle usage, we ran the system at idle for one hour on the desktop with no screen saver and took the measurement. For load measurements, Prime95's in-place large FFT's was run on all cores to make sure each and every processor was at 100% load for maximum power consumption and heat. All processors were tested on a system using as close to identical hardware as possible.
As I said above, the processors were run in as close to identical hardware as could be done. The AMD Phenom II 910e is a socket AM3 processor and the Phenom II 940 is AM2+. I was able to put the Phenom II 910e into the AM2+ setup and take some readings but I couldn't do the opposite. This was done to demonstrate the differences in the two systems so we can see a more direct comparison.
Benchmark Results: The AMD Athlon II X2 255 has an idle power draw nearly identical to that of the other AM3 processors. Under full load it draws approximately half the difference of the Athlon II X4 635. That goes to show AMD keeps the power draw fairly consistent per core.
