Westmere (formerly Nehalem-C) is the name given to the 32 nm die shrink of Nehalem. The first Westmere-based processors were launched on January 7, 2010 by Intel Corporation. Westmere designs included 1st generation Intel Core processors, including Core i3, i5, and i7. The Core i5 and i7 had been available under Nehalem, but this was the first Core i3.

Westmere's feature improvements from Nehalem, as reported:

Value Mobile

The successor to Nehalem and Westmere is Sandy Bridge.
