Temperatures

Thanks to Gigabyte's new cooler and good fan settings, the card never reaches 80°C, which unlocks additional performance at the cost of slightly increased noise levels.

GPU Temperature Comparison
	Idle	Load
Gigabyte GTX 780	37°C	72°C
NVIDIA GTX 780	37°C	81°C
NVIDIA GTX Titan	30°C	81°C

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 that we measured. We performed the measurement on the pins of a coil or a capacitor near the GPU voltage regulator.

	Core Clock	Memory Clock	GPU Voltage (measured)
Desktop	324 MHz	162 MHz	0.89 V
Multi-Monitor	324 MHz	162 MHz	0.89 V
Blu-ray Playback	324 MHz	162 MHz	0.89 V
3D Load	954 - 1072 MHz	1520 MHz	1.030 - 1.160 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 to allow 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.
