Our review of the A10-5800K APU showed that it pulled more-than-expected juice when running at maximum speed and we surmised that it was perhaps to do with the Gigabyte A85X-UP4 over-volting a touch.
The ASRock's numbers are better, especially with respect to 2D, and though the in-BIOS voltages are the same, there's clearly more energy saving going on here. We've also requested that AMD send us another A10-5800K APU sample, as our one seems to use a high-than-expected VCore.
We clearly have too much time on our hands and thus put in the A10-5700 65W APU in the socket and ran the power tests again. This lower-wattage chip returned system-wide power-draw of 26W, 69W, and 71W, respectively, for the three graphs.
