If you don't need much GPU power then having a GPU on your CPU has some benefits:
- No need for a separate component, no hassle finding a "proper" card and buying it (I.e. you only need basically a integrated GPU as a PCI card, but good look getting one, you always can get older "cheap" GPUs but then there is always the chance that because them being older the driver support started to rot.)
- Integrated GPUs tend to have reasonable good Linux driver support, at least for newish CPUs for a view years.
- No extra fan or other components which can make unwanted noise.
- One less component makes trouble shooting easier.
Tbh. if AMD would ship something like a large package (not on-die, but chiplets or otherwise packed) combining a 16+ core cpu (+hyperthreading) with a reasonable integrate GPU and ~2GB low latency RAM pro core + 3year waranty I would be quite interested in that. Some companies I worked with before would like that too as far as I can tell.
