Total 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 HAWX 2 the PC game for testing. We also tested a video
transcode using HandBrake 0.95 to see how the power draw on that was.

Total System Power Consumption

Benchmark Results: The Intel Core i7-2700k uses the same amount of power as the Intel Core i7-2600K at an idle state, but was found to use 4-7 Watts more when run at various load states. The Intel 2700K uses far less power at load than the AMD FX-8150 CPU.
