HIS Radeon HD 7970 X Turbo 3 GB Review

Value & Conclusion »

Temperatures



Temperatures are fantastic, especially when you consider the super-high frequency this card is running at. Unfortunately, fan noise is not so great. I wish HIS had hiked temperatures up a few °C for a lower noise output.

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.
