Temperatures in idle are great, but under load the card runs a bit hotter than what I expected from a triple slot cooling design.
Important: GPU temperature will vary depending on clock speed, voltage settings,
|GPU Temperature Comparison|
|Gigabyte HD 7970 SOC||46°C||85°C|
|MSI HD 7970 Lightning||39°C||76°C|
|VTX3D HD 7970||39°C||75°C|
|AMD HD 7970||45°C||78°C|
|AMD HD 7970 GHz Ed.||40°C||83°C|
cooler design, and production variances. This table just serves to provide
a list of typical temperatures for similar cards, determined during TPU review.
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.
|GPU Voltage |
|Desktop||300 MHz||150 MHz||0.85 V|
|Multi-Monitor||500 MHz||1375 MHz||0.96 V|
|Blu-ray Playback||500 MHz||1375 MHz||0.98 V|
|3D Load||1080 MHz||1375 MHz||1.25 V|
