Radeon Pro WX3200 mobile - amdgpu terrible performance

Hi. I recently obtained HP ZBook 14u G6 with Radeon Pro WX3200. I’m trying to get its GPU to work but results are quite awful. I’m not sure what to think about it. I would say that it doesn’t work but unfortunately - there is significant performance difference between DRI_PRIME=1 and DRI_PRIME=0. The problem is that performance is actually much much worse when AMD GPU is running…

I’m getting following output in dmesg and I’m not sure if it’s normal:

Is it okay? Or is this GPU completely not working and performance drop comes from fact that it’s software rendering or something like that?

Here’s my GPU:

3c:00.0 Display controller: Advanced Micro Devices, Inc. [AMD/ATI] Lexa XT [Radeon PRO WX 3200] (rev 01)

Even worse part is that having AMD gpu enabled alone (in BIOS) power throttles my CPU to some ridiculous clocks like 900mhz so for now I just keep AMD GPU disabled on BIOS level because it’s completely useless…
