RX 7900 GRE 4-way Round Up (Gigabyte + Sapphire)

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.

As mentioned, the Nitro+ pulls more power than the Pulse or Pure, hitting 295W, while the Gaming OC pulls 5W more, just scraping past 300W in my testing.

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

Interestingly, the large increases to power draw result in reduced efficiency for the Nitro+ and Gaming OC. The Pure is just as efficient as the AMD reference model, while the Sapphire Pulse is fractionally behind.
