Temperatures

Gigabyte's WindForce cooler reduces temperatures a bit and is also quieter in gaming.

GPU Temperature Comparison
	Idle	Load
NVIDIA GTX 770	35°C	80°C
Gigabyte GTX 770	34°C	76°C
ASUS GTX 770 DC II	29°C	76°C
Palit GTX 770 JetStream	31°C	78°C
GTX 680	45°C	85°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	135 MHz	162 MHz	0.85 V
Multi-Monitor	135 MHz	162 MHz	0.85 V
Blu-ray Playback	135 MHz	162 MHz	0.85 V
3D Load	1136 - 1240 MHz	1753 MHz	1.080- 1.200V

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 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.
