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.

Benchmark Results: Both the AMD A8-3850 and A6-3650 APU's have a TDP of 100W, but as you can see from the results above the A6-3650 uses less power than the A8-3850. The largest power difference between the two APU's is in 3DMark Vantage, which makes since since the two have a different number of shader cores and clock speeds. The AMD A-Series APU also has more die space dedicated to the GPU, so disabling some of it will obviously lower power requirements. All of these modern processors are very energy efficient compared to some of the ones we've seen in recent years.
