Westmere (formerly Nehalem-C) is the code name given to the
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
Celeron and Xeon
.
Technology
Westmere's feature improvements from Nehalem, as reported:
- Native six-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), 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.[3]
- Integrated graphics, added into the processor package (dual core Arrandale and Clarkdaleonly).
- 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 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.[7][8]
- Only certain higher-end CPUs support AES-NI and 1GB Huge Pages.
