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.

So far we've only tested one RX 7900 GRE model, being the reference card. Overall clock speed behaviour of this model sees the initial boost period hit just over 2300MHz before it settles down after a couple of minutes, hovering just above 2200MHz for the remainder of our stress test. Over the 30 minutes recorded, it averaged 2214MHz, a fair bit slower than the likes of the 7900 XT which typically ran at 2500MHz. It will be interesting to see if partner cards from the likes of Sapphire and PowerColor can improve on this.
