Temperatures
Temperatures are quite good. After seeing numbers in the high 90°s during recent AMD reviews, the 83°C we see from GTX 780 Ti feels almost cool. It's good to see NVIDIA bump their 80°C temperature target, which I felt was a bit too low, up to 82°C.
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 | 324 MHz | 162 MHz | 0.88 V |
---|
Multi-Monitor | 324 MHz | 162 MHz | 0.88 V |
---|
Blu-ray Playback | 324 MHz | 162 MHz | 0.88 V |
---|
3D Load | 876 - 1020 MHz | 1750 MHz | 0.987 - 1.175 V |

The card uses NVIDIA's dynamic overclocking mechanism. 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.
