We measure system-wide power draw from the wall while running the 3DMark Time Spy stress test for 30 minutes.

Total system power draw hovers around 440W for both BIOS modes.

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.

For graphics card-only power draw, both BIOS modes clearly have the exact same power target, which is why clock speed behaviour is identical between the two – the only difference is the default fan curve. Compared to the reference card, power has only increased by 16W which is hardly a significant change. Considering this card has three 8-pin connectors, I was hoping that at least the OC BIOS would really push up the power and enable higher clock speeds, but that isn't the approach Gigabyte has taken.
