Idle temperatures are fine; idle-fan-off would have certainly been possible. Under load, the card reaches its thermal limit of 84°C after a minute of gaming or so, which will cause it to lower Boost clocks, and, in effect, performance.
Clock ProfilesModern 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.
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.
|GPU Voltage |
|Desktop||135 MHz||203 MHz||0.86 V|
|Multi-Monitor||135 MHz||203 MHz||0.86 V|
|Blu-ray Playback||135 MHz||203 MHz||0.86 V|
|3D Load||1000 - 1189 MHz||1753 MHz||1.010 - 1.160 V|
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.
