Depending on the monitor configuration, be it a single monitor with 4K at 60Hz or 4K at 144Hz as well as in multi-monitor operation, AMD Radeon RX 7000 series cards can consume a lot more when idle, than one would expect.
colleagues from computer base See specially collected measures at 3840 x 2160 pixels at 60Hz compared to the same resolution at 144Hz. Instead of the 15 or 17 W of the Radeon RX 7900 XT and Radeon RX 7900 XTX at 60 Hz, the cards consume an insane 144 Hz 86 and 104 W. It doesn’t matter if the system is left completely alone or if a YouTube video is running Employment. this data computer base With Adrenalin 23.4.2, but on our forum users report that this is still the case with Adrenalin 23.5.2 from the end of May in this form.
Now Adrenalin 23.7.1 should finally eliminate the problem.
Improvements to high idle power when using displays that enable FreeSync in select 4k @ 144Hz or multi-monitor display configurations (such as 4k @ 144HZ or 4k @ 120Hz + 1440p @ 60Hz) using Radeon RX 7000 series GPUs.
– AMD’s Adrenaline changelog 23.7.1
AMD does not provide any specific information on how much power consumption can be reduced. But it took a year and a half to fix it. So far, Intel has not been able to completely eliminate a similar problem with Arc cards.
Unfortunately, we currently have no way to compare the idle consumption of a Radeon RX 7900 XT or Radeon RX 7900 XTX with the old and new driver. But maybe there will be someone among our users who owns such a card and also has a 4K monitor with high refresh rates. Using telemetry and before-and-after comparison, this can already provide information about potential changes.
Adrenaline 23.7.1 can Downloaded directly from AMD.
Update: Improvement is not always measurable
In our comments, comments regarding reduced idle power consumption were mixed. Above all, the very high consumption of the Radeon RX 7900 series is still a problem. colleagues from computer base They also measured and couldn’t find any improvement for a 4K display at 144Hz. Here the Radeon RX 7900 XTX still draws more than 100 watts, and the Radeon RX 7900 XT really isn’t any better with 86 watts.
So the problem is still not fixed in every case. Why not all systems set the card to the correct power saving state is still not clear.
