Like 720p movies, or some web browsering(it's a bit hard to measure web browsing tho, need average). I guess i should expect sub 30w then?
I am sure that part of the power savings there is how the VRM works on those boards, where it can disable phases when there is no need for them. It is possible that "out-of-the-box" the Intel BIOSes have these features enabled, but the AMD APUs do not. I measure at the 8-pin, and hte wall only, so where that actual power goes, I can only guess. Differences on installed parts, like LAN and such will ahve an effect as well. Both FM1 and FM2 APU boards are top-level Gigabyte products, A75-UD4H and the F2A85X-UP4, both have VRMs that should be capable ofthe same thing as the Intel boads.
The ASUS HD 6670 might have some fancy power-saving stuff too, I'm not sure. W1zz does GPUs, not me, so those sorts of things I gotta ask him about, even!
I didn't have a lot of time to do all those benchmarks...35 graphs, 6 systems with 8 configurations, is like over 200 tests. Plus overclocking, OS installs, blah, blah, blah...
It might be possible to get <30W, but i think that if you really want to go that low, there might be better options. Piledriver-based CPUs might make that even better...I haven't got any of those yet, so time will tell, either when AMD sends one, or I go buy one.
I do plan on having FX4100 and FX8150 in that review, so I can take a look at light desktop use power draw, for sure. I might even just add a graph with that, might be interesting info.
