For our temperature testing, we measure the peak GPU core temperature under load. A reading under load comes from running Cyberpunk 2077 for 30 minutes.
As for thermal performance, there’s again very little between the two cards. Out of the box, the BiFrost hit 71C under load, while it ran 3c hotter in the Turbo mode, likely due to increased power consumption. Intel’s Limited Edition card remains a very well built model however, and peaked at just 70C.
