Apple Silicon M1 Macs do not support eGPUs

I wonder if it would be feasible to release a product with different classes of memory. So you'd have the 8GB or 16GB in the M1 chip + an extra 48 GB elsewhere one the board.

Obviously the M1 memory would be faster, but e.g. Xbox series X has 16GB memory of which 10GB is considerably faster than the remaining 6GB.

So I guess it becomes a software challenge then... can they make the necessary changes to MacOS to manage different classes of memory efficiently?

Xeon Phi's had that - up to 16GB of ridiculously fast memory in-package and the ability to drive external memory at more pedestrian speeds.

IIRC the 16GB could be configured as an "L4 cache" for the rest of the memory.

I assume the same approach could be taken.

OTOH, it shouldn't be too complicated to just add more memory dies to the package as higher densities become available.
