Socket G2, also known as rPGA 988B is Intel's CPU socket used with their line of mobile Core i7, the successor to the Core 2 line, and also with several mobile Core i5 and Core i3 processors.

It is based on Intel's Sandy Bridge and Ivy Bridge architecture.

Like its predecessor, socket G1 systems, it can only run in dual-channel memory mode, but with data rates up to 1600 MHz (as opposed to the triple-channel mode which is unique to the LGA-1366 platform and subsequent Xeon sockets).

[2] Although nearly all motherboards using this socket are intended for mobile products like laptops, a few desktop boards using this do exist.

Supermicro, for example, produced a number of mini ITX motherboards using the QM77 chipset.
