You would think Apple would update this or put out another support page supporting what you're saying: https://support.apple.com/en-us/102363

There's also an Apple VP saying unified memory on AS doesn't leave room for DGPUs and separate VRAM.

I think this is more than just an erratum, even with newer chips. It's monopolistic behavior all too common nowadays.

don't see why they would care to put out docs on it considering macos doesn't even permit kexts anymore, there'd be no gpu drivers anyways. i figured it was obvious we're talking in the context of running linux on these things, given the parent topic.

can you link to this? my intuition is that they're speaking on whether apple would include dgpus inside AS systems like they used to with nvidia and amd chips in macbooks, which i agree wouldn't make much sense atp

There were uses for DGPUs in MacOS before AS, those uses could have continued, but Apple left no choice. It's weird how continuity wasn't as important to Apple in this case.

Whatever kernel or hardware facilities are available to Apple's own GPU driver, should be available to other GPU drivers. Anything else is myopic thinking, which I realize might be common for Apple, but it is also monopolistic.

Linux also allows userspace drivers with less performance I think, but I don't think DGPU use can be made performant because of AS hardware choices.

I am predisposed to ignoring link requests for things that can be easily googled.
