Power Consumption

We have one final data point we'd like to cover before bringing this article to a close. Our goal was to give you all an idea as to how much power each of the system configurations we tested used while idling and running under load.

Power Characteristics
Processors and Platforms

Please keep in mind that we were testing total system power consumption here at the outlet, not just the power being drawn by the processors alone.  In this test, we're showing you a ramp-up of power from idle on the desktop to full CPU load.  We tested with a combination of Cinebench R9.5 and SANDRA XI running on the CPU.

 

Our total system power consumption tests revealed an interesting trend.  For these tests, all voltages were set to 'auto' in each system's respective BIOS and Cool'n'Quiet and EIST were enabled where applicable. Our testing showed the V8 system consuming much more power than anything else while idling at the Windows desktop; almost 50W more than QuadFX and over 100W more than the QX6800.  With the processors operating under full load, however, the tables turned somewhat. Under load, the QuadFX rig - even though it had half the number of processor cores at work - consumed 24 more watts than V8.
