Temperatures



Temperatures are looking good and are in a perfectly safe range.
NVIDIA's dynamic overclocking mechanism takes temperature into account and lowers maximum boost clocks by 13 MHz each 10°C, so there would be an extra 13 MHz if the card ran 1.5°C cooler.

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 graphs 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.



We can see that both GPUs run different clocks, with the first one being typically higher clock and voltage while the second one uses more balanced clocks and voltages.



I ran the same tests on a dual card GTX 680 SLI configuration for your reference.
