With the introduction of the P55 chipest and the new socket type, 1156, comes a old but new standard. Like the CPU's of old, the newer 1156 socket CPUs use a dual channel memory controller.

But that's where it ends as far as similarities. Because unlike the CPUs of old, the newer Core i5/i7 socket 1156 CPUs, use a IMC (Integrated Memory Controller) like the 1366 socket CPU's have. The newer Core i5/i7 socket 1156 CPUs can really handle the memory very well. So well in fact these CPUs can keep up with their tri channel CPUs counter parts.
