AMD's Athlon II X4: The Baby Quads Print E-mail

Windows Power Consumption (Idle), CnQ Enabled

Idle power is nominally small but since most systems spend the most of their uptime in idle mode, it does constitute a considerable power factor. Moreover, from a CPU standpoint, low power in idle states is an important part of thermal, and by extension, acoustic management of the PC. The two new Athlon X4 idle at record-breaking 6.4 and 7.2W under idle conditions. Arguably, there shouldn't be a difference between the two and, moreover, we are pushing the resolution of our test-equipment anyway but we repeated the measurements about a dozen times over the course of several days with swapping CPUs back and forth and the results were consistent.

As mentioned on the second place, the smaller cache is a power saver, in so far, the results are what we would expect.
