AMD MI300 Supports CXL External Memory

> Something that AMD is not focusing on, but that we have seen folks talk about when we have seen MI300 platforms live over the last few weeks, is CXL. AMD supports CXL Type-3 devices with its parts. There is a path to getting more memory, and that path uses CXL memory expansion modules. That is huge.

So the MI300 it not necessarily limited to (8x)192GB. Modules like this can be added in for a huge, cache coherent memory pool.

Its slow... But still faster and much easier than external networking.
