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 used HWInfo64 sensor data to record the results. We report on the HWInfo64 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. As has been discussed in Overclocking, HWINFO 64 was used for data collection.
Power
The reference total board power of the AMD Radeon RX 7700 XT is quoted at 245W. However, SAPPHIRE quotes the SAPPHIRE PURE Radeon RX 7700 XT at a total board power of 240W on its webpage. According to our testing above, the total board power our card hit while gaming was just 215W. Therefore, it comes in under the total board power maximum rating, while gaming, which is good news. However, it is beaten by the GeForce RTX 4060 Ti 8GB video card at a much lower 158W. When we overclocked the video card, power increased by 4%, which is about the same performance increase we achieved from manual overclocking.
Temperature
You can see that that extra power is dealt with very efficiently, however. The SAPPHIRE PURE Radeon RX 7700 XT GAMING OC GPU temperatures are roughly 35% cooler than the competition. The overclocked card is cooler due to higher manual fan cycles and a very good heatsink. This is a nice graphic to demonstrate the cooling ability of the SAPPHIRE PURE Radeon RX 7700 XT GAMING OC heatsink and fan design. It keeps the GPU temp, and importantly the hot spot temp very cool under gaming scenarios. When we overclock it, temperatures also remain very cool. Kudos to SAPPHIRE on the heatsink and fan design, it works well.
