Some thoughts from anandtech: "The agreement between AMD and Intel is that Intel is buying chips from AMD, and AMD is providing a driver support package like they do with consoles. There is no cross-licensing of IP going on: Intel likely provided AMD with the IP to make the EMIB chipset connections for the graphics but that IP is only valid in the designs that AMD is selling to Intel"[1]

If EMIB is that valuable, then they should expand it to main system memory as well as NVMe flash/XPoint storage.

EMIB requires that all components can fit on a die that can be connected to the other components like the CPU using an embedded channel through the substrate. Expansion of the substrate to accommodate other components is not without costs.

For laptop purposes, wouldn't Intel just stack 8 or 16GB of main memory DRAM, like they would HBM?

Umm, probably, but NVMe is still connected via PCIe. The whole point of this deal is the EMIB connecting RAM and GPU. And its hard, EMIB connections is mostly to do with power dissipation and throughput.

I am probably out of my depth guessing why companies are doing this with NVMe. Maybe its just that the market does not exist for it maybe its just the cost...
