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 Graphics, while 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, Celeron and Xeon, and includes directX 10.1, and openGL 2.1.

Technology

Westmere's feature improvements from Nehalem, as reported:

  • Native six-core (Gulftown) and ten-core (Westmere-EX) processors.{{cite web|last1=Valich|first1=Theo|title=Intel says no to 28nm, focuses on 22nm: Ivy Bridge/Haswell & Larrabee|url=http://brightsideofnews.com/news/2009/4/16/intel-says-no-to-28nm2c-focuses-on-22nm-ivy-bridgehaswell--larrabee.aspx|access-date=23 March 2015|archive-url=https://web.archive.org/web/20110708093954/http://www.brightsideofnews.com/news/2009/4/16/intel-says-no-to-28nm2c-focuses-on-22nm-ivy-bridgehaswell--larrabee.aspx|archive-date=2011-07-08|date=2009-04-16}}
  • A new set of instructions that gives over 3x the encryption and decryption rate of Advanced Encryption Standard (AES) processes compared to before.{{Citation

  • Delivers seven new instructions (AES instruction set or AES-NI), out of which six implement the AES algorithm, and PCLMULQDQ (see CLMUL instruction set) implements carry-less multiplication for use in cryptography and data compression.{{Citation |title=Carry-Less Multiplication and Its Usage for Computing The GCM Mode – Intel Software Network |date=2008-04-11 |url=http://software.intel.com/en-us/articles/carry-less-multiplication-and-its-usage-for-computing-the-gcm-mode |access-date=2009-03-01}}
  • Integrated graphics, added into the processor package (dual core Arrandale and Clarkdale only).
  • Improved virtualization latency.{{Citation |title=Westmere 32nm to improve Nehalem features |author=Fuad Abazovic |publisher=Fudzilla.com |date=2008-09-16 |url=http://www.fudzilla.com/news/processors/12649-westmere-32nm-to-improve-nehalem-features |access-date=2009-03-01}}
  • New virtualization capability: "VMX Unrestricted mode support," which allows 16-bit guests to run (real mode and big real mode).
  • Support for "Huge Pages" of 1 GB in size.

  • TDP includes the integrated GPU, if present.
  • Clarkdale processors feature 16 PCIe 2.0 lanes, which can be used in 1x16 or 2x8 configuration.
  • Clarkdale and Arrandale contain the 32 nm dual core processor Hillel and the 45 nm integrated graphics device Ironlake, and support switchable graphics.{{Citation
