AMD Radeon RX 7900 XT and RX 7900 XTX GPUs have been troubling with energy usage since the beginning. AMD has addressed these problems and is working round-the-clock to provide a working solution. AMD had released a driver that introduced optimized power usage for specific workloads.
AMD Radeon RX 7900 series driver increases power efficiency in video playback mode and partially when cards are idle.
Before the driver was released, the RX 7900 XT and RX 7900 XTX cards reported 71W AND 81W consumption, respectively. However, after the driver update, there was a significant improvement in power usage, now going up to 46W and 54W.
This might not be that major compared to AMD and NVIDIA’s popular graphics cards. The Radeon RX 6900 XT only required 34W while the RTX 4080 needed merely 30W power.
Surprisingly, AMD had not mentioned improved gaming power efficiency in the driver details. It was discovered that the driver helped RX 7900 GPUs consume less power when the framerate was limited.
For example, Doom Eternal at 1440P on the RX 7900 XTX reported a 57% efficiency improvement and up to 34% for the RX 7900 XT.
AMD is working on a unified structured driver for its RDNA2/RDNA3 GPU. Their latest driver (23.1.1), which is exclusively for RDNA3 GPUs, is not too different from their 22.12.2 driver. Hopefully, we get an optimal solution soon enough.
