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 were run on all cores to make sure each and every processor was at 100% load for maximum power consumption and heat.
Benchmark Results: The AMD Phenom II X4 980 Black Edition had the second to lowest idle power consumption. Sitting Idle at only 100 Watts the Phenom II X4 980 Black Edition was second only to the AMD Phenom II X6 1100T Black Edition. The load power consumption numbers of the AMD Phenom II X4 980 Black Edition, which is drawing 216 Watts, place it in the second spot as well, though this time it is second to the Intel Core i5 2500K which was drawing only 171 Watts at full load!
