AMD optimizes the power consumption of RX 7900 series graphics cards at no load or while watching videos
AMD’s RX 7900 series graphics cards will experience abnormal power consumption when the GPU is idle or playing video. At present, the graphics card driver that AMD has launched recently has optimized this situation, reducing the power consumption of the graphics card when it is idle and playing video to a certain extent.
According to reports, the Software Adrenalin Edition 22.12.2 driver released by AMD not long ago has optimized the above situation. For example, in the scene of playing a 4K60 video on YouTube, before optimization, the power consumption of the Radeon RX 7900 XT is 71W, and the power consumption of the Radeon RX 7900XTX is 81W. After the new driver is optimized, the power consumption of the two graphics cards in the same scenario is reduced to 46W and 54W respectively. However, the previous generation Radeon RX 6900 XT is only 34W, and Nvidia’s GeForce RTX 4080 is even lower at 30W. The power consumption of these two graphics cards still needs further improvement.
According to computerbase, in game performance, the power consumption of RX 7900 XT and Radeon RX 7900XTX under the new driver has also been reduced. In the 2K 144Hz game scene, the power consumption of the Radeon RX 7900 XTX is reduced from 248W to 158W, and the power consumption of the Radeon RX 7900 XT is 169W. However, in this game scene, the power consumption of the GeForce RTX 4080 is 139W, which is obviously better. In general, in the 2K test scenario with graphics card driver 22.12.2, the energy efficiency of Radeon RX 7900 XTX is increased by 57%, and the energy efficiency of Radeon RX 7900 XT is increased by 34%. Of course, this test result is only applicable to 2K resolution.
AMD optimizes the power consumption performance of the RX 7900 series graphics card, and one of the specific results is reflected in the temperature change, which is also very helpful to the performance of the graphics card.
