Power draw
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 A Plague Tale: Requiem (4K/2160p) for this testing.
Interestingly, we do observe some difference in power draw – the GamingPro OC drew just under 370W in our testing, ahead of the Gaming OC on 366W, while the Suprim was even more efficient at just 350W – perhaps due to its beefier VRM?
Performance per watt
Combining the power draw values shown above with the performance data, we present performance per watt for each graphics card tested:
That lower power draw means the Suprim is top dog when it comes to performance per Watt, but the differences are very small between all three cards on test today.
