Westmere (formerly Nehalem-C) is the code name given to the 32 nm die shrink of Nehalem. While sharing the same CPU sockets, Westmere included Intel HD, UHD and Iris Graphics, Nehalem did not.

The first Westmere-based processors were launched on January 7, 2010, by Intel Corporation.

The Westmere architecture has been available under the Intel brands of Core i3, Core i5, Core i7, Pentium and Celeron.
