Temperatures
Temperatures are excellent, even with the card cooling itself passively in idle. Gaming also sees temperatures well below NVIDIA's 80°C temperature limit. Clocks will be reduced slightly, although never below the base clock, if the card gets any hotter than the limit. Our graph further down the page details the card's clock distribution.

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 we measured. We performed the measurement on the pins of a coil or a capacitor near the GPU voltage regulator.
| GPU Clock | Memory Clock | GPU Voltage (measured) |
---|
Desktop | 135 MHz | 162 MHz | 0.86 V |
---|
Multi-Monitor | 135 MHz | 162 MHz | 0.86 V |
---|
Blu-ray Playback | 135 MHz | 162 MHz | 0.86 V |
---|
3D Load | 1113 - 1291 MHz | 1753 MHz | 1.037 - 1.200 V |

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.
