https://arstechnica.com/gadgets/2022/12/amd-acknowledges-high-power-use-in-rx-7900-gpus-plans-driver-fixes/ > AMD's Radeon RX 7900 XTX and 7900 XT GPUs are still fresh, and as with most products based on new architectures, there are some early bugs to work out. > A driver update released earlier this week (version 22.12.2, the second driver release for the RX 7900-series in as many weeks) addresses high power use during video playback when using the cards' built-in media decoding hardware. Other problems have been acknowledged but not fixed yet, including "high idle power [...] when using select high resolution and high refresh rate displays."
