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 GeForce RTX 2080 SUPER has a total board power of 250W, while the GeForce RTX 4080 SUPER has a total board power of 320W. In our testing, while playing a game, the GeForce RTX 2080 SUPER hit just above that, while the GeForce RTX 4080 SUPER is actually well under its quoted total board power, according to GPU-Z data while playing a game. In this testing, the GeForce RTX 4080 SUPER uses 9% more power than the GeForce RTX 2080 SUPER. Considering it’s 150%+ faster, that’s a heck of an efficiency result.
Looking at just GPU Chip Power, the GeForce RTX 4080 SUPER uses 11% more power than the GeForce RTX 2080 SUPER, for the GPU chip.
Both video cards are Founders Edition models. What’s interesting is that the GeForce RTX 4080 SUPER actually runs cooler at 60.8c.
Looking at GPU Hot Spot, the RTX 4080 SUPER is running a lot cooler at 70.4c, while the GeForce RTX 2080 SUPER is allowed to reach 105c.
