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.

Interestingly, power draw is slightly lower than the rated TGP in Cyberpunk 2077, as it hit 212.7W, compared to the Founders Edition which drew 226W.

Combining the power draw values shown above with the performance data, we present performance per Watt for each graphics card tested:

That does mean overall efficiency is slightly increased compared to the Founders, but not in a overly significant way.
