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.
Starting our look at the dual-BIOS functionality of the GameRock OC, we can see the Performance BIOS runs a fair bit faster, hitting 1925MHz on average. This is 59MHz ahead of the Silent BIOS, meaning both are actually faster when compared to the Gigabyte Eagle OC, which only has one BIOS mode.
