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 while running under load.
 

Power Characteristics
Processors and Platforms


Please keep in mind that we were testing total system power consumption here at the electrical 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 9.5 and SANDRA XI running on the CPU.

Before reading too far into these power consumption numbers, we need to clarify the results. The Core 2 Duo E6750 was tested on an Asus P5K Deluxe P35-chipset based motherboard that is chock full integrated peripherals.  The remaining Core 2 processors were all tested on an Intel D975XBX2 motherboard which is based on the 975X Express chipset and isn't nearly as loaded at the P5K Deluxe. The P35 chipset has shown to consume more power than the 975X and the additional integrated peripherals on the P5K all need power as well.  These differences account for the overall power consumption deltas represented above.

Putting aside that information, we see the E6750 consumed 39 more watts under load than it did while idling.  In comparison the E6700 consumed 34 more watts under load, and the X6800 45 more.  So while the E6750 / P35 platform consumed more power as a whole, the processor itself was right on-par with the older E6700.
