AMD’s Radeon RX 7900 XTX and 7900 XT GPUs are nonetheless contemporary, and as with most merchandise based mostly on new architectures, there are some early bugs to work out.
A driver replace launched earlier this week (model 22.12.2, the second driver launch for the RX 7900-series in as many weeks) addresses excessive energy use throughout video playback when utilizing the playing cards’ built-in media decoding {hardware}. Different issues have been acknowledged however not fastened but, together with “excessive idle energy […] when utilizing choose excessive decision and excessive refresh charge shows.”
German evaluate web site Computerbase (through Tom’s {Hardware}) seen these points and others when testing the playing cards; the location additionally measured considerably increased energy consumption than the RX 6900 sequence and Nvidia’s GeForce RTX 3000 and 4000 sequence playing cards when sitting idle on the Home windows desktop with a pair of related 60 Hz 4K screens.
The brand new drivers’ launch notes do not point out excessive energy use in multi-monitor setups, however they point out a number of different issues with these configurations. The drivers repair crashing points that may have an effect on programs with 4 screens related, they usually acknowledge (however don’t repair) app crashes that may happen when utilizing Radeon Tremendous Decision (RSR) and video stuttering points that may happen when a number of screens are related.
Whereas AMD promised “additional energy effectivity enhancements” for the GPUs in “future [driver] releases,” the corporate did not present extra data on what particular issues it was planning to repair or how a lot these fixes would assist cut back energy consumption. Our evaluate discovered that the RX 7900 GPUs usually eat as a lot or barely extra energy than Nvidia’s competing RTX 4080 whereas gaming. Nevertheless, the drivers appear to focus totally on lowering energy in instances the place it is supposed to be low, like when it is decoding video or rendering the Home windows desktop.
