Temperatures



Temperatures look to be optimized to stay just below 80°C, as that is the point at which NVIDIA's driver introduces additional throttling to keep temperatures down. Overclocking will break that limit, so performance gains might not be as big as possible.

Given the data, I would have liked MSI to adjust fan spin up a tiny bit for roughly 77°C under load, giving the card a bit more headroom. That said, the low noise levels are really nice and probably justify losing 0.5% (educated guess) in performance.

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.

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

For the graph below, we recorded all GPU clock and GPU voltage combinations of our 1920x1080 resolution benchmarking suite. The plotted points are transparent so they can add up to indicate more often used values. A light color means the clock / voltage combination is rarely used and a dark color means it's active a lot.
