Here we present the average clock speed for each graphics card while running the 3DMark Fire Strike Ultra stress test 20 times. We use GPU-Z to record the GPU core frequency during the Fire Strike Ultra runs. We calculate the average core frequency during the entire 20-run test to present here.
With a rated boost clock of 1800MHz, our testing shows the Gigabyte OC 6G ran almost 60MHz faster than this, with an average frequency of 1857MHz. This is 57MHz slower than the MSI Gaming X 1660 Ti, and as our game testing showed, this works out to a real-world performance difference of 1-2FPS.
