7800 XT power-limited despite GPU load
Playing Assassin’s Creed: Shadows, my 7800 XT will be pegged at 100% utilization but won’t draw more than 160-180W despite its TBP of around 260W. In contrast, my other system with a the new RX 9070 will pull its full 220W without issue, and performance is noticeably better as a result.
Based on some google-fu, it seems like this is an RDNA3 bug dating back around 2 years that “should” be resolved in newer kernels, yet it seems to persist on my rig. I went to desktop mode and ran “ujust update” so I should be on the latest stable Bazzite packages.
Has anyone encountered a fix for this? The resulting FPS drops are so intrusive that I’m debating playing the game on PS5 instead, or swapping my older RX 6800 back in.
Full System config:
Ryzen 7600X
Radeon RX 7800 XT
32GB DDR5
Gigabyte B650 ITX board
2TB Samsung 980 Pro
850W Corsair SF850 SFX
