Power consumption
Power numbers are considered for the system running the chip's IGP. Extra voltage means that the idle power goes up by over 25 per cent.
And 2D load by 17 per cent.
The biggest power-draw drain comes from the integrated graphics. Remember that the CPU and iGP are over-volted, and 3DMark Vantage stresses both. The upshot is that power increases by almost 50 per cent. For what it's worth, the stock-clocked UD5H pulls a few more watts than the comparison duo, which is understandable given that it has a broader feature-set.
