Intel's Core i7 line of processors, the successor to the Core 2 line, was released in November of 2008. It is based on Intel's Nehalem architecture and with it came the 1366-pin "Socket B", which like it's predecessor, uses the LGA socket configuration. Later followed an updated LGA-1156 socket, which moved the QPI and PCI-express controller off of the Northbridge and on to the CPU. As a result of the lower pin count it's trade off is LGA-1156 systems can only run in Dual-channel memory mode, as apposed to Triple-channel that is unique to the LGA-1366 platform (and subsequent XEON sockets). The Nehalem's mobile variant was released on September 23, 2009 in the form of the various i7-x20QM and i7-x20XM models, followed by the the i7-x40QM and i7-x40XM models on June 21, 2010. These were dubbed "Extreme Mobile" processors and used the new Clarksfield core, which maintained the same 45nm manufacturing process as the desktop-based Nehalems. Nehalem received a die shrink on January 7th of 2010, under the core name of Westmere. With the Intel GMA HD Graphics Ironlake core packaged onto the CPU substrate, but not integrated directly to the processor die, it goes on to create the Arrandale-based line. Current processors utilizing this package are the: Core i7-6x0M,6x0LM & 6x0UM, Core i5 5x0M, Core i3-3x0M and finally the Pentium P6000 and Celeron P4500 which were released on March 28, 2010.

Technical specifications
Placeholder for someone to fill in who knows more about this sort of things.
 * Pins arranged in a 36 x 35 grid array
 * 18 x 15 size grid removed from the center
 * Utilization of cam actuated retention mechanism
 * The r in rPGA refers to "Reduced pitch" which is 1mm x 1mm in this socket design. <?>Presumably in regards to the angle in which the socket clamps down on the processor's pins to make contact and also retain the chip..
