In case you consider using the AMD pstate frequency scaling driver...

Make sure to use amd_pstate=active. I tried amd_pstate=passive originally but, even with performance governor it would severely throttle at high-fps gaming. I often got 20-30 FPS lower than what the active or even the default acpi driver gave me during spiderman remastered.

There is also amd_pstate=guided but I haven't tried that. CPU is 5800x3D and I usually play at 80-140FPS in that game so I'm thinking the load was not managed well by the passive one.
