Power and Temperature and Clock Speed – RTX 4070
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.
We know that the TGP of the GeForce RTX 4070 is 200W, and NVIDIA suggests typical average gaming power is around 186W. Well, this isn’t too far off. The board power we experienced was 197W, just shy of the 200W TGP, and GPU Chip power is just 171W. At these power levels, the GeForce RTX 4070 runs more efficiently than the RTX 3070, RTX 3070 Ti, and Radeon RX 6800. The GeForce RTX 4070 uses 14% less power than the GeForce RTX 4070 and 31% less power than the GeForce RTX 3070 Ti, which it beat in performance quite a bit every single time. This is an amazing efficiency boost gen-to-gen at the same price point.
Coinciding with the lower power draw, the GeForce RTX 4070 Founders Edition also has exceptional temperature results. It runs the coolest on GPU and Hot Spot temps. At 66.3c GPU temp, it’s cooler than the RX 6800, RTX 3070, and RTX 3070 Ti. Compared to the RTX 3070 Ti the RTX 4070 is 15% cooler.
The GPU Boost on the GeForce RTX 4070 Founders Edition is 2475MHz. According to our real-world game testing, we are finding that the GPU Boost boosts the GPU here up to 2775MHz maximum, and it will dynamically drop down to 2745MHz. Therefore, at 2775MHz it is operating 300MHz above the Boost Clock, or 12% higher than the default clock from the Founders Edition.
