AMD used to have much a much better hardware story for compute. I don't know how it looks now, but nVidia have absolutely stolen the market due, in part, to their excellent software -- even on Linux.
My only experience of compute on AMD was a FirePro v7900 -- an expensive, workstation-class card. With both the latest, and the 'workstation-class' Catalyst Linux drivers, my LuxMark tests came out very vast, but very red.
With nVidia, I can simply add a repo to my Ubuntu machine and have the latest stable drivers every time I do a dist-upgrade. If I want a solid, tested CUDA dev environment, I can install the CUDA repo and do likewise.
AMD have to make sure the end-user experience with these cards is as smooth as that, and that everything works.
I really hope AMDGPU-PRO is that experience. I haven't tried it yet, so I can't comment.
It's easy to dismiss enthusiasts / hobbyists / developers / gamers as a 'small market'. There was no 'pro gamer' market until ~10 years ago. Now there are entire companies built off the back of it. AMD cannot continue to leave a sour taste in end-users' mouths, otherwise there might not be any left soon.
