Temperatures

Temperatures are probably on the high side because of the extremely simple heatsink used on the AMD reference design. The fan is already running at quite high speed, which not only makes it noisy but is also indicative of the AMS reference heatsink being a bit too weak. Custom board design will certainly have their own, better coolers.

Clock Profiles

Modern graphics cards have several clock profiles that are selected to balance power draw and performance requirements.

The following table lists the clock settings for important performance scenarios and the GPU voltage we measured. We performed the measurement on the pins of a coil or a capacitor near the GPU voltage regulator.
