RDNA3 Power Management/clockspeed bug

When starting a game or other demanding 3D application the GPU seems to be powerlimited and/or clockspeed limited. On my case it was only drawing 270W power and the clockspeeds were howering around 2450 Mhz when they usually hower around 2600 - 2800 mhz territory.

  • CPU: AMD Radeon 7 7800X3D

  • GPU: 03:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Navi 31 [Radeon RX 7900 XT/7900 XTX/7900M] [1002:744c] (rev c8)

  • System Memory: 32 GB 6000 Mhz CL32 DDR5

  • Display(s): Gigabyte M32U, Samsung 1440p 165HZ monitor

  • Type of Display Connection: DP, DP

  • Distro name and Version: CachyOS, Arch Linux (Tried both)

  • Kernel version: 6.10.8

  • Custom kernel: N/A

  • AMD official driver version: N/A

To reproduce the issue just start a game on a 7900 XTX and see the clockspeeds and the powerdraw.

Above is a image of a game running unlimited FPS but the clockspeed and powerdraw are low. The stock powerlimit is 315W.
