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 4060 has a TGP of 115W in the specification. In our testing, the ZOTAC GAMING GeForce RTX 4060 8GB Twin Edge OC White Edition resulted in a 120W board power according to GPU-Z, so this is in line with where it should be, remember this video card has a factory overclock and boosts higher. At 120W board power, it is much more efficient than the Radeon RX 7600 and last generation GeForce RTX 3060 12GB. Compared to the Radeon RX 7600 the ZOTAC GAMING GeForce RTX 4060 8GB Twin Edge OC White Edition uses 27% less power than the Radeon RX 7600 and yet performs faster. Compared to the previous generation RTX 3060 12GB the power savings is 31%.
Overclocking the ZOTAC GAMING GeForce RTX 4060 8GB Twin Edge OC White Edition only added 5 more Watts, or 5% more power, which is very minor for the performance uplift. Even at 126W for board power, overclocked, it is still the most efficient video card on this graph.
When testing temperature, the ZOTAC GAMING GeForce RTX 4060 8GB Twin Edge OC White Edition ended up on the warmer side, with a GPU temp of 71c and a Hot Spot of 85c. It was cooler than the Radeon RX 7600, which still ran hotter by a few degrees on the GPU and four degrees on the hot spot. However, the EVGA RTX 3060 12GB did run cooler than the ZOTAC GAMING GeForce RTX 4060 8GB Twin Edge OC White Edition. Intel Arc A750 ran a little cooler, but it has a beefier heatsink and fan. This was all with the fans on automatic control, which was quiet while gaming. When we overclocked the ZOTAC GAMING GeForce RTX 4060 8GB Twin Edge OC White Edition we cranked the fans up to 80%, and when we did this the temperatures came down a lot and the video card was the coolest here. We had GPU temps only at 68c and the hot spot came down a few degrees, and remember this was with an overclock.
GPU-Z Sensor Data
The first screenshot above (on the left) is of GPU-Z at Default, and the second screenshot of GPU-Z (on the right) is with the video card overclocked. We can see that the GPU Voltage is 1.0650V in both scenarios. At default, the fan speeds rose to 52% on automatic, in our overclocking we raised them to 80%, which was more than sufficient as it lowered the temperatures quite a bit even overclocked.
