Looks like the amount of onboard memory on these cards is quickly approaching what some people have as their total system memory now.

That's not even on-board, but on-die (or extremely close) - more like a cache.
"Workloads with >16GB of data can take advantage of the DDR4 memory in Knights Landing, which is rumored to have a maximum capacity of 384GB."

Cheers,

How is this being delivered (as hardware)? Is it being designed as a PCI card, a socket-compatible coprocessor for dual-socket Xeon syetems - or as a standalone system? It's pretty interesting tech - I'm hoping that we see more use of EDRAM in their other chips too, since so much performance is constrained to cache limits. The Crystalwell i7 with Iris Pro graphics embedded has 128MB of EDRAM as a L4 cache, seems to give a real boost in certain cases

It seems like all three option will be possible.
