Enter The Dragon: AMD Phenom II X4 940
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.
When coupled to AMD's 790GX motherboard platform, the new Phenom II X4 940 and 920 proved to be quite power friendly. They offered the lowest idle power consumption of the bunch and peak consumption was lower than all of the Intel-based systems with the exception of the lower-clocked Core 2 Quad Q9400.
