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.
Interestingly, despite have a lower rated clock speed than the RX 6800 XT, in practice we saw the RX 6800 achieving higher frequencies. It’s not a massive difference, but across our 30 minute stress test the GPU averaged exactly 2200MHz. This is a frequency increase of over 400MHz compared to the RX 5700 XT, so it is highly impressive to see how far AMD has increased clock speed while remaining on the same 7nm process.
