Socket G1, also known asrPGA 988A, is a CPU socket introduced byIntel in 2009 for the mobile variants of the first-generationIntel Core processors.[1] It is the successor toSocket P, and the mobile counterpart toLGA 1156 andLGA 1366.
The first CPUs for the Socket G1 platform were released on September 23, 2009, in the form of the i7-720QM, 820QM, and 920XM.[2] These CPUs use theClarksfield core, which maintained the same45 nm manufacturing process as the desktopNehalem architecture. On January 4, 2010, the range was expanded with Core i3, i5, and i7 processors using the32 nmArrandale core and based on theWestmere architecture.[3] On March 28, 2010, low-end Arrandale-based CPUs were released as the Pentium P6x00 series and Celeron P4x00 series. Further Clarksfield-based processors were released as the i7-740QM, 840QM, and 940XM on June 21, 2010. All Socket G1 processors, except for the quad-core i7 CPUs have theIntel HD Graphics Ironlake core packaged onto the CPU substrate.
