AMD Athlon X2 7750 and 5050e Dual-Core Processor ReviewMon, Dec 15, 2008 - 8:00 AM
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 as Corsair doesn’t currently offer an Intel Core i7 water block retention plate.
Results:The AMD Athlon X2 5050e consumed 109W at idle and 152W at load with AMD Cool’n’Quiet enabled and 115W at idle and 152W at load with Cool’n’Quiet disabled. With the Corsair Nautilus 500 Water Cooler being used with Cool’n’Quiet the idle reading was 120W with a load of 160W.
The AMD Athlon X2 7750 consumed 129W at idle and 190W at load with AMD Cool’n’Quiet enabled and 145W at idle and 189W at load with Cool’n’Quiet disabled. With the Corsair Nautilus 500 Water Cooler being used with Cool’n’Quiet the idle reading was 141W with a load of 204W.
