Power and Temp
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 GPU-Z sensor data to record the results. We report on the GPU-Z sensor data for “Board Power” and “GPU Chip Power” when available for our Wattage data. For temperature data, we report the GPU (Edge Temp of the GPU or Package Temp) as well as Hot Spot (Junction Temperature) when available for our temperature data.
NOTE – As we mentioned earlier, we are using GPU-Z version v2.51.0, which does not currently support Radeon RX 7900 XTX. Therefore it does not currently report board or GPU power Wattage, so we do not have that information in this review. We will update our review with those results when we can, but we can report the temperature testing.
It was no secret that AMD’s last generation video cards ran hot, the Radeon RX 6900 XT is the hottest running card on our graph at 83c GPU temp and 98c hot spot. Well, the new AMD Radeon RX 7900 XTX is a huge improvement in temperatures. The GPU only ran up to 66c and the hot spot at 88c. That’s a 20% reduction in GPU temp and a 10% reduction on hot spot temps. At those temps, it runs on par with the GeForce RTX 4090 FE with its massive cooler for GPU temp. On hot spot it’s about on par with GeForce RTX 3090 FE. It runs cooler than every video card on GPU temp except for the RTX 4080, which uses an overkill cooler.
We did experience the back and top of the video card getting quite hot, however. The backplate, as we mentioned, helps to dissipate heat. Using a temp probe we found the backplate to get up to 56c in some places, and the top of the video card got as hot as 60c when pushing a game for a long time really hard. These are pretty hot surface temps, especially on the backplate. It does show that the backplate is helping to aid in cooling, but it also shows us you want to have good case airflow because all this heat is dumped inside your case.
GPU-Z Sensor Data
According to GPU-Z the fan speed increased up to 65% at these temperatures, or 1739RPM. The GPU Voltage was 0.916V.
