AMD Athlon II X4 620 and Athlon II X4 630 Processor Review

Power Consumption

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. Both processors were tested on a system using identical hardware.

Results: The power supply that we have dedicated to just our CPU testing systems recently failed and is no longer in production. Since we had to the change power supply all the power consumption results of the processors will have to be re-tested. For the time being we ran power consumption tests on some of the AMD Phenom II and Athlon II processors to see how they stack up. The new Athlon II X4 processors have nearly identical power consumption numbers and run at ~195W at full CPU load.
