Power consumption - IGP PC
So how does it all play out from a power-efficiency angle? We swapped out the standard 1kW PSU for a Zalman 400W for this test.
Wonderfully low idle power-draw figures. It's notable that adding a discrete GPU to the Intel system increases power-draw by 36 per cent.
The AMD chip has a higher-rated TDP than the Intel Core i3 - 100W vs. 65W - but that's based on full APU usage. Focussing in on the CPU part, the pull from an at-mains meter is decent for all four configurations.
As is gaming, though, repeating ad nauseam, adding in a low-end discrete card pushes up power-draw on the Core i3 system.
