We use Nvidia PCAT to measure power draw of the graphics card only, with readings from both the PCIe slot and the PCIe power cables combined into a single figure. We use Cyberpunk 2077 (1440p) for this testing.
Power draw hit the rated TGP almost exactly, as we saw 220.1W power draw during testing.
Combining the power draw values shown above with the performance data, we present performance per Watt for each graphics card tested:
That means performance per Watt is identical to the JetStream OC and Nvidia Founders Edition, though not quite as good as the Aero OC – but we're talking fine margins.
