shining LEDs (now in 4K scenarios)

I suspect that in kernel 4.19 power limit decreased in 4 times on Vega GPU
I remember that earlier in the GPU bound scenarios all LED are shining. Now I have never seen more than two LEDs shining at the same time even when GPU is 100% loaded (I see this by HUD monitoring)
I even forgot when I heard last time when turbine roared.

From the point of view of audio comfort, this is all great, but the feeling that video card was became weaker does not leave me, and it upsets. Unfortunately, I have nothing to compare I don't like use old kernels because they have a lot of not fixed old bugs.
