Temperatures

Temperatures are good, in the typical range of other GTX 680 cards we have tested.

Important: GPU temperature will vary depending on clock speed, voltage settings,
cooler design, and production variances. This table just serves to provide
a list of typical temperatures for similar cards, determined 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 performed the measurement on the pins of a coil or a 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 and 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.



Unlike other GTX 680 cards, where we see a staircase pattern covering a wide range of clock and voltage combinations, the KFA² GTX 680 OC uses only a few clock states.
