--- Comment #1 from alekshs@hotmail.com --- I think I discovered what's the issue by playing with a utility called RyzenAdj.
With RyzenAdj when setting the igp freq to 200 from 400 it doesn't do much for power consumption. It's when I play with the CPU-GPU speed parameter (fabric speed?) that power consumption goes down significantly.
So apparently power_dpm_force_performance_level to low sets both MHz and fabric speed lower. The first wouldn't make sense to affect CPU performance, the second is known to affect it - so after thinking about it more, I don't think it's a bug.
