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) as well as the Hot Spot (Junction Temperature) when available for our temperature data.
We now get a look at the cost of all that speed. The MSI GeForce RTX 4090 SUPRIM X draws 6% more wattage than the AMD RX 7900 XTX when overclocked 11% more. Is that bad? Well, it’s more. At this level, it is indeed academic.
The temperature however shows just how good the MSI RTX 4090 SUPRIM X heatsink handles all the heat from that power and performance. What is remarkable is that the fan cycle was left on AUTO and the overclocked temperatures and default temperatures are nearly identical. Yes, the fans did spin up slightly in our overclocked trials, from 36 to 39%. The fans were silent, needless to say.
