Yes, it was retired for EL7 but it is also was useless nowadays as it 
only supported older hardware and for older RHEL releases ( it was no 
longer compatible with the  version of Xorg included in EL7.4 ). It can 
still be used on RHEL6 for now ( I use it on the very system I am typing 
from )

I have not yet seen an ATI chipset non functional with the open source 
driver. However on several occasions it was not optimal, such as not 
really accelerating anything or not being able to drive multiple 
monitors at full resolution. As you suspect it is quite possible that 
the chipset you are interested in is not fully supported by the open 
source driver for now.

     That chipset seems to be supported by 
https://support.amd.com/en-us/download/workstation?os=Linux+x86_64#pro-driver. 
To cut a long story short, AMD started ( last year, IIRC ) to provide "a 
few" rpms ( read that as "dozens" ) which supposedly work with the 
latest incarnations of EL6 and EL7. Based on the name ("amdgpu-dkms") 
the relevant parts might be able to be rebuilt, in a proper env, once 
the kernel is updated thus avoiding the need for a reinstall. Due to 
lack of need ( I only use / have access to APUs), I was never able to 
test those packages. And as you probably guessed already, given the 
sheer number of packages and the lack of hardware to test on, for now I 
am not able ( and not interested, to be fully honest ) to repackage 
those drivers.
