You can expect to see Ivy Bridge roughly a year after Sandy Bridge January 5th launch. The desktop platform around this new CPU is called Maho Bay and the chipset that will power it is Panther Point PCH. Naturally there will be a mobile version as well.
The graphics is still a part of CPU and it is a DMI chipset and has FDI support. Last time we checked FDI standard for Flexible Display Interface, something that enables you two or more display outs.
Intel promises much better energy efficiency and this is natural as we are talking about 22nm transistors and a lot of optimisation.
