So here's something for people who've been "misinformed" with the power consumption of the Gigabyte GA-F2A88XN-WIFI mITX motherboard.
I brought my power meter home over the weekend to test this, as I was calling BS on the article that was showing abnormally high power consumption figures.
They used an A10-6800K Processor in that review and while that is a little less power efficient than Kaveri, there's definitely something up with their numbers.
I'm testing in an Overclocked environment and will do the same tests as shown in the graph further up the page. (I'll do some stock tests at some point)
I'll also include some real world results of my own.
Test setup
AMD A10-7850K Overclocked to 4.2ghz CPU, 1000mhz iGPU
Thermalright AXP-200 cooler
Gigabyte GA-F2A88XN-WIFI motherboard (F4a Bios)
2x4gb Team Xtreem LV DDR3 2400 Cas 10, 12, 12, 31, 2T
256gb Samsung 830 SSD
500gb HGST 2.5" Storage Drive 7200rpm
160w Pico Psu /w 192w power brick
Silverstone Milo ML06B case
USB mouse and keyboard
Windows 8.1 Pro 64 bit
iGPU on AMD catalyst 14.1 beta
AMD Chipset driver 13.20
All C states enabled and APM enabled
Onboard WIFI enabled (using even more power)
Figures given are total system power consumption measured at the socket with my trusty Kill A Watt meter.
Here's the tests to Compare with the graph, although it's not clear on their methodology for their 3DMark Firestrike testing, I'd concur that scaled up, my overclocked testing would be similar to their results clock for clock if they'd posted proper numbers and not some skewed kind of average.
Idle power consumption (after 5 mins idle) = 28w
3DMark Firestrike
Graphics Test 1 = 103.8w Peak
Graphics Test 2 = 102.4w Peak
Physics Test = 101.7w Peak
Combined Test = 114.3w Peak
Cinebench 11.5 = 104.7W Peak
Somehow their CPU intensive test (Cinebench 11.5) vastly differs from mine, like I've said previously Kaveri is a little more power efficient than Trinity, but there is something badly wrong with their result.
This particular test result is the one responsible for the "Misinformation", they didn't even test the board with a Kaveri APU.
Real world results and observations of my own.
Borderlands 2 1080p, Medium Settings, No AA
Co-op play with 3 other friends
Buttery smooth, no jitters
Complete system power draw ~125w with the odd peaks of ~130w.
Starcraft 2 1080p Medium Settings No AA
Single player game, jitter free, scrolls nicely
Complete system draw 117w
1080p 10gb Blu-ray rips, played back through XBMC (DXVA)
Complete system power draw = 62w
Got Guiminer working, 112k hashrate (at 1000mhz iGPU)
Complete system power draw = 96w (shows it's working the iGPU nicely)
Stock clocks testing and Underclocking / Undervolting / cTDP function to be tested some time soon
