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.

Westmere's feature improvements from Nehalem as reported:

Native six-core (Gulftown) and ten-core (Westmere-EX) processors.^[1]
A new set of instructions that gives over 3x the encryption and decryption rate of Advanced Encryption Standard (AES) processes compared to before.^[2]
- Delivers seven new instructions (AES instruction set or AES-NI) that will be used by the AES algorithm. Also an instruction called PCLMULQDQ (see CLMUL instruction set) that will perform carry-less multiplication for use in cryptography.^[3] These instructions will allow the processor to perform hardware-accelerated encryption, not only resulting in faster execution but also protecting against software targeted attacks.
Integrated graphics, added into the processor package (dual core Arrandale and Clarkdale only).
Improved virtualization latency.^[4]
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.

Westmere CPUs

TDP includes the integrated GPU, if present.
Clarkdale processors feature an integrated PCIe 1 x16.
Clarkdale and Arrandale contain the 32 nm dual core processor Hillel and the 45 nm integrated graphics device Ironlake, and support switchable graphics.^[7]^[8]
