Temperatures are excellent. Unfortunately, fan noise is not so great. I wish HIS had hiked temperatures up a few °C for a lower noise output.
|GPU Temperature Comparison|
|HIS HD 7950 X² Boost||34°C||61°C|
|Sapphire HD 7950 Vapor-X||45°C||66°C|
|Sapphire HD 7950 Flex||38°C||67°C|
|ASUS HD 7950 DC II||32°C||65°C|
|MSI HD 7950 TF III||32°C||59°C|
|AMD HD 7950||43°C||75°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 ProfilesModern 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||0.97 V|
|Multi-Monitor||500 MHz||1250 MHz||0.95 V|
|Blu-ray Playback||501 MHz||1250 MHz||1.06 V|
|3D Load||950 MHz||1250 MHz||1.09 V|
