Value & Conclusion »

Temperatures

Temperatures are good in both idle and load. NVIDIA's new Boost 2.0 algorithm is tuned for an operating temperature of 80°C, which is a good balance between noise and heat.

GPU Temperature Comparison
	Idle	Load
NVIDIA GTX 780	37°C	81°C
Gigabyte GTX 780	37°C	72°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 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	0.86 V
Multi-Monitor	324 MHz	162 MHz	0.86 V
Blu-ray Playback	324 MHz	162 MHz	0.86 V
3D Load	860 - 1007 MHz	1520 MHz	1.025 - 1.160 V

The card uses NVIDIA's dynamic overclocking mechanism which will have the card 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.
