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. It should be noted that the Core i7
processors used a Thermaltake BigWater 760i water cooler and the rest
of the systems used a Corsair Nautilus 500 water cooler.
it came to power consumption the Intel Core 2 Quad Q8200S used less power than the Intel Core 2 Quad Q6600 that it traded blows with in nearly all of the performance benchmarks. At load the Q8200 used 21W less power than the Q6600, which was nice to see.
