Sapphire RX 6600 XT Pulse Review

We measure system-wide power draw from the wall while running Cyberpunk 2077 for 30 minutes.

Total system power draw comes in at 301W with the Pulse installed in our i9-10900K test system. There's basically no difference between the Pulse or the Gaming OC Pro.

We also 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. This provides us with significantly more accurate data to work with as it is measuring only the GPU power, and not total system power which is a fundamentally imprecise measurement.

In terms of graphics card only-power daw, again we are looking at a very minimal difference between both RX 6600 XTs. The Pulse drew 158.7W at 1080p, compared to 161.1W for the Gaming OC Pro. Both are highly efficient designs and you can't really quibble about 2.4W either way.
