AMD FirePro W7000 poor graphics performance, Fedora 28
Hi Folks.
I have been researching for days on this and while I am sure it is a dead horse I am beating here, I am just running in circles and I am hoping someone could point me in the right direction.
HP Z620 Workstation
32 GB ECC ram
Intel Xeon E5-2660, 2.2 Ghz x8
AMD FirePro W7000, 4GB GCN 1.0
Fedora 28, standard installed Fedora repo
Samsung UHD 4k monitor (prehaps the issue?)
I have read the AMDGPU pages regarding my particular card and the AMD provided drivers are not compatible with Fedora 28. Originally I was using Red Hat 7.5 and even there I was unable to install the driver (always received some type of lib error that was not resolved using yum).
Overall the system is quite laggy on graphics. The Gnome Activities > Show Applications animation looks like 5 frames per second - I can live with that, but using Gimp is quite painful. Generally doing things such as resizing docked panels reminds me of using a grossly underpowered machine. Screen redraws are very slow etc.
Perhaps mistakenly I purchased the W7000 graphics card because before using the HP Workstation I had a home built PC with an AMD R9 380 graphics card from which I was able to install the amdgpu drivers and all was hunky-dory. Unfortunately that card is not compatible with the power supply in this HP which provides only 6 pin for the GPU power (the old card needed an 8 pin) - since I had that nice AMD card experience, I upgraded the HP's original nvidia Quadro 2000 (1GB) thinking I would have a smooth experience.
Can anyone offer any advise? I am certainly not afraid of reading documentation etc. I just haven't found documentation that seemed relevant to Fedora. Of course if the answer is burning the 240 euros on this recently purchased, used, W7000 as well - I suppose so be it - I am just not looking to spend several hundred dollars on a graphics card.
Thank you!!!! Hxh
