Temperatures



Idle temperatures are good because the fan does not stop in idle. During gaming, temperatures are quite high, reaching 84°C - which isn't alarming, but doesn't exactly boost confidence in the reference-design cooler, especially since it's kinda noisy, too.

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 these measurements on the pins of a coil or capacitor near the GPU voltage regulator.

The card uses a new version of AMD's dynamic overclocking mechanism. It will dynamically adjust clock and voltage based on render load, temperature, and other factors.

For the graph below, we recorded all GPU clock and GPU voltage combinations of our 1920x1080 resolution benchmarking suite. The plotted points are transparent, which allows them to add up to indicate more often used values. A light color means the clock/voltage combination is rarely used and a dark color means it's active more often.
