Intel integrated memory controllers into Nehalem architecture, but it doesn’t mean the chipset will be small：Intel shows us a slide, saying Ibex Peak will be a single chip core-logic solution.

Graphic will directly connect to CPU, so does DDR3 memory. So the chipset will only in charge with input output equipments and display. Compare to graphic and memory, I/O and display is not bandwidth intensive so Intel keeps DMI links on Ibex Peak.
