Temperatures



Temperatures are great. MSI's cooler does an excellent job here. Given these low temperatures I see some additional potential to quieten down the fan even further, but I guess MSI focused on lower temperatures to make overclockers happy.

Important: GPU temperature will vary depending on clocks, voltage,
cooler design and production variances. This table just serves to provide
a list of typical temperatures for similar cards, reached during TPU review.


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 that we measured. We measure on the pins of a coil or capacitor near the GPU voltage regulator.

The card uses NVIDIA's dynamic overclocking mechanism, which means it will dynamically adjust clock and voltage based on render load, temperature and other factors.

For the graph below, we recorded all GPU clock, GPU voltage combinations of our benchmarking suite for the 1920x1200 resolution. The plotted points have transparency, so they can add up to indicate more often used values. A light color means the clock/voltage combination is rarely used, a dark color means it's active a lot.
