Power Consumption

For all of the performance tests, we disable all power-saving technology in order to give us a consistent set of results, and to give us best-case performance numbers - even though technologies such as Intel's SpeedStep might only take microseconds to kick in, that can make a difference in some tests.

However, for the power consumption tests we re-enable everything in order to gauge real-world power draw. The power draw is measured via a power meter at the wall, so the numbers below represent the total system power draw from the mains, not the power consumption of a CPU itself. Measuring the power draw of any individual component in a PC is tricky to impossible to achieve.

Idle Power Consumption

For this test, we leave the PC doing nothing but displaying the Windows 7 desktop (with Aero enabled) for a few minutes and record the wattage drawn from the wall via a power meter.

Load Power Consumption

To generate a realistic load power consumption figure we need to load both the CPU and GPU portions of the processors. To do this we use Prime95 to load the CPU and Unigine's Heaven benchmark to load the GPU.
