In order to get an idea of a GPU's power draw when gaming, we record peak power consumption during 3D Mark Time Spy. 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 (3,840 x 2,160).
Thermal output is measured using Unigine's Valley 1.0 benchmark. The GPU is installed in a closed but fairly well ventilated case (Corsair Carbide Series Air 740). We leave all GPU fan profiles and settings as they come 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 (3,840 x 2,160).
