Socket G1, also known as rPGA 988A, is a CPU socket introduced by Intel in 2009 for the mobile variants of the first-generation Intel Core processors.{{Cite web |title=Intel Core i7-600, i5-500, i5-400 and i3-300 Mobile Processor Series Datasheet — Volume One |url=https://cdrdv2.intel.com/v1/dl/getContent/600229 |url-status=dead |archive-url=https://web.archive.org/web/20220316193553/https://d2pgu9s4sfmw1s.cloudfront.net/UAM/Prod/Done/a062E00001XMU0KQAX/c2e88386-f1e1-153c-9ef4-a61fcee2c333?Expires=1647459652&Key-Pair-Id=APKAJKRNIMMSNYXST6UA&Signature=EVJJRD8QD-C3LbgFghtagWMB~y0sXNTeFqNMgr0XHL4H3GTSkOPspEnk79yfW5XPTbgtf~qP-4nTNxcbJpyoiWrW3~r5ef-73FZmdPKRB-vYa6x9YLcrRaxuINFTbxnY9nIoXey6ZYPv4Hg6eH9N6Sb9H-~BBpz5tbFwVs0PQ31MuBSXyrsTngiFC2Xk2htCAZiZfD9-pcdSdilQKTiOGwVVBYAZYAcFVIwS-J7ybJegQr~6uup08PpyCTVOIzeN9xk5WSvjiggfTQeBA7LXOiSa4lu7D5d62tllSPTdhM4UQ1si-DOC5R3t3rk9BbjYvMHKd1eGLmWK6-pqlyTd1A__ |archive-date=2022-03-16 |access-date=2022-04-28 |website=Intel.com}} It is the successor to Socket P, and the mobile counterpart to LGA 1156 and LGA 1366.
History
The first CPUs for the Socket G1 platform were released on September 23, 2009, in the form of the i7-720QM, 820QM, and 920XM.{{Cite web |last=Walton |first=Jarred |date=2009-09-23 |title=Mobile Core i7 920XM, Clarksfield: Nehalem on-the-go |url=https://www.anandtech.com/show/2845 |access-date=2022-04-28 |website=AnandTech}} These CPUs use the Clarksfield core, which maintained the same 45 nm manufacturing process as the desktop Nehalem architecture. On January 4, 2010, the range was expanded with Core i3, i5, and i7 processors using the 32 nm Arrandale core and based on the Westmere architecture.{{Cite web |last=Lal Shimpi |first=Anand |date=2010-01-04 |title=Intel Arrandale: 32nm for Notebooks, Core i5 540M Reviewed |url=https://www.anandtech.com/show/2902 |access-date=2022-04-28 |website=AnandTech}} 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 the Intel HD Graphics Ironlake core packaged onto the CPU substrate.

Technical specifications
- Pins arranged in a 36 × 35 grid array
- 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.{{Cite web|url=https://www.molex.com/molex/products/datasheet.jsp?part=active/0479890132_PROCESSOR_SOCKETS.xml&channel=Products&Lang=en-US|title=Molex Connector Part Number - 47989-0132|website=molex.com|access-date=2019-01-24}}
- Socket G1 systems can only run in dual-channel memory mode, compared to the triple-channel mode of LGA 1366, as a result of the lower pin count.
