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.
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 R10 and SANDRA XII running on the CPU.
While idling and under load, the Phenom powered test systems drew more power than all of the Intel powered systems; only the Quad-FX rig consumed more. Due to the relative immaturity of the platform, however, we suspect the AMD Athlon 64 X2 and Phenom systems' power consumption numbers are skewed a bit on the high side. What's interesting to note is that with double the execution cores and much more cache, the Phenom 9700 draws 30 more watts than the Athlon 64 X2 4600+ while idling an 53 more watts while under load.
