We'd like to cover a few final data points before bringing this article to a close. Throughout all of our benchmarking and testing, we monitored how much power our test systems consumed using a power meter. Our goal was to give you all an idea as to how much power each configuration used while idling and while under a heavy workload. Please keep in mind that we were testing total system power consumption at the outlet here, not just the power being drawn by the processors alone.
The new Phenom II X4 965 Black Edition has a 140 watt TDP--15 watts higher than the 955. As such, you would expect it to consume more power than the previous flagship, and you would be correct. The Phenom II X4 965 Black Edition consumed slightly more power at idle and 15 more watts under load.
