Here we present the average clock speed for each graphics card while running A Plague Tale: Requiem 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.
As for clock speed behaviour, I tested both trhe Performance and Quiet BIOS of the ASRock Taichi. The Quiet BIOS uses a reference clock speed, whereas the Performance BIOS comes factory overclocked, and as we can see there is a difference of about 100MHz in the real world.
In fact, the Quiet BIOS averaged 2726MHz, compared to 2830MHz for the Performance BIOS. We can also see this is significantly faster than the RX 9070 (non-XT), which clocks in at more like 2350MHz.
