How To Make The RX 9070 XT Extremely Power Efficient
7The RX 9070 XT now has outstanding power efficiency characteristics, and can still go all the way up to 330 watts if needed under very heavy loads.
The higher power limit in this situation improves stability, because unbalanced limits can cause overheating. With these settings it is using the power more fully, so there’s almost no additional heat.
At default the RX 9070 XT is constantly trying to boost to around 3500 MHz, which can help in some limited situations, but is highly power inefficient. It's now effectively matching the official max boost clocks of 2970 MHz.
The core clocks will usually not go over 3000 MHZ in more demanding situations, so the additional 500 MHz is of limited use here. You also get a 5% boost to performance due to better efficiency.
For more competitive settings, such as at lower resolutions, you will lose some performance due to lowered boost clocks. However, I prefer more demanding games, at high resolutions, so it was an easy decision.
The temperature displayed on the extreme right is Hot Spot. There's also a 5-10% loss in performance in the video benchmarks due to recording with Radeon ReLive.
