Here we present the average clock speed for each graphics card while running Cyberpunk 2077 for 30 minutes. We use GPU-Z to record the GPU core frequency during gameplay. We calculate the average core frequency during the 30 minute run to present here.
The reason we see such little difference in real-world gaming performance between all three RTX 3090s tested, is because there's not that much of a difference in operating clock speed. The AMP Extreme Holo, for instance, averaged 1878MHz using its default Amplify BIOS, which is only 35MHz faster than the Gigabyte Eagle OC and 48MHz faster than the ASUS TUF (Performance BIOS.) Again, it's not nothing – but it's not as big of a gap as the rated clock speeds would have you think.
