My understanding is that Knights Landing will be a standalone chip,
i.e., you can stick it into a single-socket motherboard. I don't
know if this socket will be the same as a standard Xeon Socket,
which would be rather neat, but I think that's the reasoning
behind marketing it as a "Xeon Phi".
It follows that system memory will be DDR and not GDDR.
