ZOTAC GeForce GTX 670 AMP! Edition 2 GB Review

Value & Conclusion »


Temperatures are great, thanks to the triple slot cooler. Given these temperatures and the noise levels I think it would have been better to have a more balanced approach which provides lower noise at the cost of slightly increased temperatures.

Important: GPU temperature will vary depending on clocks, voltage,
cooler design and production variances. This table just serves to provide
a list of typical temperatures for similar cards, reached 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 measure on the pins of a coil or capacitor near the GPU voltage regulator.

GPU Voltage
Desktop324 MHz162 MHz0.99 V
Multi-Monitor324 MHz162 MHz0.99 V
Blu-ray Playback324 MHz162 MHz0.99 V
3D Load1006-1176 MHz1652 MHz1.037-1.175 V

The card uses NVIDIA's dynamic overclocking mechanism, which means it will dynamically adjust clock and voltage based on render load, temperature and other factors.

For the graph below, we recorded all GPU clock, GPU voltage combinations of our benchmarking suite for the 1920x1200 resolution. The plotted points have transparency, so they can add up to indicate more often used values. A light color means the clock/voltage combination is rarely used, a dark color means it's active a lot.
