Power and Temperature
To test the power and temperature we perform a manual run-through in Cyberpunk 2077 at “Ultra” settings for real-world in-game data. We use GPUz sensor data to record the results. We report on the GPUz sensor data for “Board Power” and “GPU Chip Power” when available for our Wattage data.
In terms of board power draw reported by GPUz, we find the typical scaling we’d expect. The GIGABYTE GeForce RTX 3090 GAMING OC video card utilizes the most Wattage at 357W. What is surprising though is how close the GeForce RTX 3080 Ti FE is to it at 356W. They are basically equal. Though keep in mind our GIGABYTE RTX 3090 is a factory overclocked custom video card. That means compared to the GeForce RTX 3080 FE the new RTX 3080 Ti FE consumes about 10% more board power.
Looking at GPU chip power draw (which is different from board power draw, we are only looking at the GPU here) we can see the AMD Radeon RX 6900 XT runs away with the highest power demand. What is also interesting though, is that the new GeForce RTX 3080 Ti FE’s GPU consumes slightly more power than the GIGABYTE GeForce RTX 3090 GAMING OC GPU. This is because of the higher consistent clock speed the RTX 3080 Ti FE runs at.
The new GeForce RTX 3080 Ti FE stays rather cool at 74.2c. It runs cooler than the GeForce RTX 3080 FE which hit 80.5c. This is a major plot point because the GeForce RTX 3080 Ti FE uses the same board format and same cooler configuration, and also has a higher specification. The hot spot temperature on the GeForce RTX 3080 Ti FE was 83.1c while it was 91.1c on the GeForce RTX 3080 FE. The GIGABYTE GeForce RTX 3090 GAMING OC is running the coolest because it has a robust custom cooler from GIGABYTE. Its hot spot was 72.3c. The hottest running card was the Radeon RX 6900 XT, it’s hot spot was 96c.
