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 actually a bit lower with the JetStream OC than the 4080 Super Founders Edition, by about 15W. It's not a massive difference, but I wonder if this is behind the JetStream OC's inability to clock as high as the other two 4080 Super cards tested.

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

Overall efficiency is identical to the other 4080 Supers however, at the top of the chart.
