Socket G2, also known as rPGA 988B (there are Socket G/rPGA 989 sockets that can take Socket G2/rPGA 988B), is Intel's CPU socket for their line of mobile Core i7, the successor to the Core 2 line. It is based on Intel's Sandy Bridge architecture. Its predecessor, socket G1 systems, can only run in dual-channel memory mode, as opposed to the triple-channel mode which is unique to the LGA-1366 platform (and subsequent Xeon sockets).

Technical specifications

• Pins arranged in a 35 × 36 grid array (it is not compatible with G1 socket due to different placing of one pin)
• 18 × 15 size grid removed from the center
• Utilization of cam actuated retention mechanism
• The r in rPGA refers to "Reduced pitch" which is 1mm × 1mm in this socket design.
