Multiple lines of code supposedly from the latest macOS Catalina 10.15.4 beta suggest that Apple might shift over to AMD chips.

What are the odds this is just vestigial code in the graphics driver for the AMD cards already in use?
First off, they're talking about the MacOS code, not the graphics driver code. Although it's possible that Apple's coders might include everything in the OS code, since even Apple has numerous hardware options available across the different hardware generations that work with each version of MacOS, I strongly suspect that they handle this the same way that Microsoft, Linux, & other OS vendors do, & the graphics driver is a stand-alone set of code.
But even if not...you're talking about graphics processors vs. CPUs. The graphics drivers put out by AMD have nothing to do with the CPUs -- you can run an AMD GPU in an Intel-based system, remember, just like you can run an nVidia GPU in an AMD-based system -- so they wouldn't reference AMD's CPUs in the graphics driver code.

My understanding was integrated graphics connect to the CPU through the PCIe bus in a very similar to a descrete card. (I could be wrong it happens from time to time). On the same silicon but it's still through the PCIe controller. So there may be shockingly few differences between the drivers for the integrated vs the dedicated graphics of the same architecture other than the integrated doesn't have dedicated memory.I'm quite certain that these drivers are not what gets installed for your discrete GPU drivers either ... but someone with an AMD APU can correct me - I think the APUs require their own special graphics drivers, as opposed to the standard "adrenaline" discrete driver package.

We're only talking about APUs here ... The CPU needs specific graphics drivers to use the GPU inside the CPU. Else whats the point of the APU?
