AMD GPU's are great for general purpose computing (with no issues about web-drivers, etc like NVIDIA) and mainly work OOB as GUI.
The issues with the AMD GPU's are more to do with specific Apps that encode/decode video that macOS does not handle very well (read bugs). In fact Apple have (with the latest update) now disabled h/w encode/decode for some of the AMD GPU's.
I’ve been reading up a bit in this and the same problem was happening in Windows and users had to remove and update to new AMD drivers. So AMD launched RX cards without driver support and then corrected it for Windows apps.
This really is ironic seeing as how Apple has said the new Metal2 is supposed to use the graphics cards more effectively and take the load off of the CPUs. But this encoding/decoding issue is contrary to that stated goal.
There may be another aspect to it as well. Apps for macOS being created for all users and many Macs don’t have a dedicated GPU so maybe they just focused on the Intel side because all macs currently support have this in common?
