We are now able to find out what kind of power is being used by our test system and the associated graphics cards installed. Keep in mind; it tests the complete system (minus LCD monitor, which is plugged directly into an AC wall socket).
At stock speeds both platforms are identical, it's when we overclock we got a huge surprise.
The new ASRock 785G was able to run with less power. That's right, clocked higher and running with less power, we did the tests over and over to see if it was a faulty reading but no, it was confirmed.
As a new measure, we are now monitoring the heat generation from the key components on the motherboards, this being the Northbridge, Southbridge (if it contains one) as well as the Mosfets around the CPU. The results are recorded at idle and load during the power consumption tests.
Heat generated by the 785G was also lower at stock and overclocked speeds. It seems that AMD has put alot of work into this chipset and ASRock has gotten the best out of it.
