In order to get an idea of a GPU's real world power draw, we run our Crysis 3 2,560 x 1,600 benchmark, which is currently our toughest single screen GPU test. We use a watt meter to measure the maximum total system power draw during the test, and also take an idle reading at the Windows desktop (2,560 x 1,600).

Thermal Performance (Idle and Gaming)
Thermal output is measured using Unigine's free Heaven 3.0 benchmark, as its DirectX 11 features will stress all parts of a modern GPU. We leave all GPU fan profiles and settings as they come. We use the default Unigine settings with a resolution of 2,560 x 1,600 and leave the benchmark running for ten minutes so that temperatures plateau. We record the peak GPU temperature using GPU-Z, and present the data as the delta T (the difference between the GPU temperature and the ambient temperature in our labs). We also take an idle reading at the Windows desktop (2,560 x 1,600).
