Temperatures are amazing and better than any other GTX 780 card we tested so far. Here, the new DC II cooler definitely shines, but I would have liked lower noise levels instead of such drastically reduced temperatures.
Important: GPU temperature will vary depending on clock speed, voltage settings,
|GPU Temperature Comparison|
|ASUS GTX 780 DC II||35°C||67°C|
|EVGA GTX 780 SC||34°C||74°C|
|Gigabyte GTX 780||37°C||72°C|
|NVIDIA GTX 780||37°C||81°C|
|NVIDIA GTX Titan||30°C||81°C|
cooler design, and production variances. This table just serves to provide
a list of typical temperatures for similar cards determined during TPU review.
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 that we measured. We performed the measurement on the pins of a coil or a capacitor near the GPU voltage regulator.
|GPU Voltage |
|Desktop||135 MHz||162 MHz||0.88 V|
|Multi-Monitor||135 MHz||162 MHz||0.88 V|
|Blu-ray Playback||135 MHz||162 MHz||0.88 V|
|3D Load||888 - 1019 MHz||1502 MHz||1.037 - 1.162 V|
The card uses NVIDIA's dynamic overclocking mechanism, which 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 1920x1200 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.
