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).
Power draw from the wall on most systems has gotten much better despite the fact that components are getting more greedy for voltage. Many manufacturers are putting in power management systems that really can drop down the idle power needs pretty significantly. In this regard the Foxconn A9DA-S does very well.
The power draw from the wall under load is also pretty good here. It is still not as low as the Intel system, but then again, we are using a 140 Watt CPU in the AMD system which puts things into a different ball game.
As a new measure, we are now monitoring the heat generation from the key components on the motherboard; 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.
The heat generated by the Foxconn A9DA-S is very minimal. Maybe the fancy heatsink is actually doing something besides looking good.
Even under load we see that the A9DA-S can keep the Northbridge cool.
