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 fans, video cards and hard drives. 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 was run on all cores to make sure each and every processor was at 100% load for maximum power consumption and heat. All processors were tested on a system using the same hardware; the exception is the Intel system.
The AMD Phenom II X6 1100T Black Edition draws a peak 18 Watts more than the Phenom II X6 1075T does under a full load and at idle. This could be from the speed bump or just the plain fact that every processor is just a bit different. Let’s face it though, if you are buying the biggest, fastest processor from AMD I doubt that power consumption is your biggest concern.
