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 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.[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 the Intel HD Graphics Ironlake core packaged onto the CPU substrate.
