Here we present the average clock speed for each graphics card while running the 3DMark Time Spy stress test for 30 minutes. We use GPU-Z to record the GPU core frequency during the Time Spy runs. We calculate the average core frequency during the 30 minute run to present here.
Here we start our assessment of the Gaming OC's dual-BIOS functionality. In terms of clock speed, behaviour between the two is identical – as it turns out, the only difference between the OC and Silent BIOS is a slightly tweaked fan curve. That does affect thermals, and thus clocks, to a very slight degree, but you'd not notice the difference when gaming. Either way, both BIOS run about 80MHz faster than the reference card, explaining the 2% difference to overall performance we saw in our game benchmarks.
