ASUS F1A75-M Pro System Power Consumption

CPU 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 identical power supplies, Solid-Sate Drives, Memory kits and motherboards from the same company. 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. Curious about other test  scenarios, we decided to 3DMark Vantage the performance preset and took the maximum power consumption during the first GPU test. We also tested a video transcode using HandBrake 0.95 to see how the power draw on that was.

ASUS F1A75-M Pro System Power Consumption

Benchmark Results: The Intel Core i5-2500k Processor is a quad-core processor that has a maximum TDP of 95 Watts, while the AMD A8-3850 APU has a TDP of 100W. One would expect the two processors to use roughly the same amount of power, but we saw huge differences at an idle and measurable differences at load.
