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 fan, video card and hard drive model. 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 POV-Ray 3.7 was run on all cores to make sure each and every processor was at 100% load. All of the systems used identical hardware minus the motherboard and processor.
Results: The AMD 780G was found to use 35% less power in an idle state than the AMD 690G. At load the 780G was also lower, but load testing was done using POV-Ray. This is important to point out as the IGP isn’t being used. If the graphics engine was used this power consumption number would obviously be slighty higher. When running S.T.A.L.K.E.R. the 780G system would peak at 95W, so it consumed roughly 3W more with the GPU being used.
