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 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.
The TGP of the NVIDIA GeForce RTX 4080 and RTX 4080 SUPER is 320W. We can see that without overclocking, the GeForce RTX 4080 SUPER actually uses less power than the GeForce RTX 4080, by 5%. What’s interesting, is that when we overclock the GeForce RTX 4080 SUPER power increases exactly 5% matching the GeForce RTX 4080 on power draw, but not exceeding it! That’s one efficient video card. Even when overclocked, the GeForce RTX 4080 SUPER uses 13% less power than the Radeon RX 7900 XTX.
When looking at GPU Chip Power the overclocked GeForce RTX 4080 SUPER uses 7% more power than at default, but still manages to come in under the power draw of the GeForce RTX 4080.
When it comes to temperatures, it is no surprise that the Radeon RX 7900 XTX runs the hottest at 70c, while the GeForce RTX 4080 SUPER FE and RTX 4080 FE run at cooler temperatures. Overclocking the GeForce RTX 4080 SUPER only increased temperatures by 3%.
This is also no surprise above, the Radeon RX 7900 XTX runs with a very hot Hot Spot temperature of 91c. Overclocking the GeForce RTX 4080 SUPER increases the Hot Spot GPU temp by 4%.
Below, you can see the default settings, and on the right screenshot the overclocked settings. You will notice that the GPU Voltage remained the same in our overclock at 1.0750V. We kept the fan speed on automatic, and it automatically ramped up a couple of percent when overclocked, so the noise profile remained the same, which was very good and quiet. The memory also remained at the same temperature despite our memory overclock to 24.5Gbps.
