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.
