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 play some Sleeping Dogs and took the maximum
power consumption during a benchmark session.
Benchmark Results: The idle power consumption between our two platforms was 6 Watts which is a pretty decent difference and showed the GIGABYTE A75-D3H drawing less power. Once we started loading up the system the tables were turned. The GIGABYTE A75-D3H was pulling 22 Watts more power in Prime95 and 13 Watts more power in sleeping dogs.
