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 the Hot Spot (Junction Temperature) when available for our temperature data.
Power
In this chart we can see that the ASUS TUF Gaming Radeon RX 7900 GRE OC Edition exceeds the power rating in both conditions, but especially overclocked. (although we do increase the power limit there.) The MSI GeForce RTX 4070 Gaming X TRIO is the most efficient by 34% and 28%. Both of the AMD cards are power users in fact.
Temperature(s)
Looking first at the GPU temperatures, even though the XFX Speedster MERC 319 Radeon RX 7800 XT Black Edition is using a bunch of power it stays very cool. A testament to the cooler on that very well-built video card. The ASUS TUF Gaming Radeon RX 7900 GRE OC Edition is no slouch either. Doesn’t matter if the card is overclocked, the temperature is a cool 63C. No doubt due to the undervolting when overclocked. Surprisingly, only 8% warmer than the power-sipping MSI GeForce RTX 4070 Gaming X TRIO.
Turning to the “Hot Spots” the ASUS TUF Gaming Radeon RX 7900 GRE OC Edition does heat up, especially when overclocked (as can be understood). No doubt due to the extra power usage. Still, the cooling fans never had to ramp up higher than 32% and were silent.
