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.
Power draw is slightly higher than the FE, but only by 12 or-so Watts, so it's nothing to worry about.
Performance per Watt
Combining the power draw values shown above with the performance data, we present performance per Watt for each graphics card tested:
Overall performance per Watt is still level with the RTX 5070 FE, though the RX 9070 is the clear winner in this instance.
