Is the Big Deal about this having what used to be different cards/chips sharing a cpu-style insanely fast bus, instead of trickling stuff over pcie or dram channels? If that is the case, the advantage of this will depend on the amount of bus saturation to be eliminated. Should be interesting. Everything works on Infiniti fabric!

That’s the advantage over having multiple packaged chip on a traditional PCB. The advantage over an SoC is that you can have different subsystems on decoupled development schedules and different process nodes all come together on the same “chip.”

Seems to be the opposite.
With HBM2 being used in AMD's (and NVidia's) high-end products, it seems like the DRAM Channels are going to require an expensive interposer.
But "what else" can benefit from an interposer? If your RAM requires it, are there cheaper or more efficient designs that are built out of a network of chiplets on an interposer, as opposed to building out huge chips all the time?
AMD is already forced to build an interposer for Vega64. Might as well research other uses of it.
