Temperatures

GPU Temperature Comparison
	Idle	Load
MSI GTX 660 TF III	30°C	59°C
ASUS GTX 660 DC II TOP	31°C	66°C
ZOTAC GTX 660	34°C	69°C
Gigabyte GTX 660 OC	32°C	60°C
HD 7870	29°C	69°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	0.86 V
Multi-Monitor	324 MHz	162 MHz	0.86 V
Blu-ray Playback	324 MHz	162 MHz	0.86 V
3D Load	1033 - 1160 MHz	1502 MHz	1.050 - 1.175 V

The card uses NVIDIA's dynamic overclocking mechanism, meaning 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 voltage combinations of our benchmarking suite for the 1920x1200 resolution. The plotted points have transparency - they can 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.
