The latest drivers greatly improve the energy efficiency of the Radeon RX 7900

It seemed that the graphics Radeon RX 7900 XT and XTX They were going to be a blow to NVIDIA, but the reality is that AMD ended up missing more than hitting an opportunity that many considered golden. Among the problems that have been detected in the latest graphs from the red giant are consumption and energy efficiency, aspects that the company has tried to improve with version 22.12.2 of its Adrenalin drivers for Windows.

In addition to introducing fixes for specific games, which is common to see from AMD, NVIDIA and more recently Intel, what stands out the most about the Adrenalin 22.12.2 drivers is the implementation of optimizations around the use of energy for certain loads. work, including some games. Of course, AMD has not specified any specific scenario.

The information on the improvement in efficiency has been obtained thanks to the German medium ComputerBase, which has published some consumption and performance data of the launch versions and the December 2022 version of the Adrenalin drivers on the Radeon RX 7900 XT and XTX. The energy consumption playing YouTube videos has gone from 71 and 81 watts to 46 and 54 respectively. with the video game Running Doom Eternal at 1440p, the RX 7900 XT saw an efficiency improvement of 34% vs. 57% for the RX 7900 XTX. In fact, just looking at the graph of the performance per watt with Doom Eternal you can see that, according to the data provided by ComputerBase, the improvement in efficiency is more than evident.

It is important to note that AMD has not yet released a unified driver for its RDNA 2 and RDNA 3 graphics cards, as Adrenalin version 23.1.1 only works with the latest generation Radeon GPUs (RDNA 3/RX 7900), although, according to what they say in ComputerBase, it is not that they provide a worthwhile improvement for now.

The RX 7900 XT and XTX graphics are encountering more than desirable problems, in addition to the fact that at least there are units that were marketed with a still immature architecture. We’ll see if AMD manages to come back based on updating the drivers, which is not uncommon to see, but the downside is that, when the GPUs start to give their best, their business cycle has ended or is about to to do so, so in the end it always trails behind NVIDIA.

We take this opportunity to remember that Adrenalin 22.11.2 WHQL is causing problems in the RX 6000 (RDNA 2) graphics, to the point of completely breaking them and rendering them useless, so from MuyComputer we recommend avoiding the use of said version of the drivers for Radeon.
