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."
German review site Computerbase (via Tom's Hardware) noticed these issues and others when testing the cards; the site also measured significantly higher power consumption than the RX 6900 series and Nvidia's GeForce RTX 3000 and 4000 series cards when sitting idle at the Windows desktop with a pair of connected 60 Hz 4K monitors.
