Temperatures



Idle temperatures are fine with even the idle-fan-off feature we love so much. In gaming, temperatures are low, just not as low as with MSI's GTX 980 Ti Lightning, which is also faster.

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 as 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 we measured. We performed these measurements on the pins of a coil or a capacitor near the GPU voltage regulator.

The card uses NVIDIA's dynamic overclocking mechanism, GPU Boost 2.0. 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 a lot.
