As a small data point: I'm running a Sapphire Pulse Radeon RX560 on
-STABLE with the amdgpu driver and it works like a charm.

I bought the card to quietly drive a 4K-screen, and it works very well
for that.

glxinfo shows:

Extended renderer info (GLX_MESA_query_renderer):
    Vendor: X.Org (0x1002)
    Device: Radeon RX 560 Series (POLARIS11 / DRM 3.10.0 / 11.2-
PRERELEASE, LLVM 5.0.1) (0x67ef)
    Version: 18.0.0
    Accelerated: yes
    Video memory: 4019MB
    Unified memory: no
    Preferred profile: core (0x1)
    Max core profile version: 4.5
    Max compat profile version: 3.0
    Max GLES1 profile version: 1.1
    Max GLES[23] profile version: 3.1

I'=C3=84ve not done any benchmarking, since I don't really need 3D
performance. Blender and kdenlive run smoother than before (with
Intel), but I really don't use either heavily.

Cheers, Mathias

Oh, I'm just noticing this is with drm-next-kmod-4.11.g20180224, not
drm-stable-kmod on -STABLE from May 3:

FreeBSD marcopolo 11.2-PRERELEASE FreeBSD 11.2-PRERELEASE #1 r333211:
Thu May  3 20:39:20 CEST 2018

Probably historical reasons. I guess stable shoud work too...
