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.
Keep in mind, that we were not able to increase the Power Target on the NVIDIA GeForce RTX 3090 Ti Founders Edition video card, therefore the TDP remains the same. The only increase is in GPU clock speed and memory clock speed. The power numbers show the overclocked GeForce RTX 3090 Ti FE to be practically the same, or even a bit lower than the default.
It may seem odd at first glance, but also keep this in mind, we have the fans at 100% and the GPU and memory is running a lot cooler overclocked, some voltages could be different. Even though the clock speeds are higher, the power demand is generally the same without any Power Target changes.
With the same TDP, the same limits are in place on power, and we just don’t see it increase by only overclocking the core and memory frequencies. Performance was obviously increased, as our testing shows, and the GPU frequency is also increased, as our GPU Frequency over time graph showed on page one. The GPU is running faster, but it just isn’t drawing any more power to do so without a Voltage increase or Power Target increase. This behavior is unique most likely to the Founders Edition, with no Power Target differences or options.
With the fans at 100% with this overclock the GPU and Hot Spot temperatures are much reduced. The Founders Edition cooling configuration is well built for the GeForce RTX 3090 Ti GPU.
