ERROR: "atype" is missing!

Westmere was the microarchitecture for Intel's 32 nm process for desktops and servers. Westmere was introduced in 2010 as a process shrink of Nehalem which introduced a number enhancements.

For desktop and mobile, Westmere was branded as 1st Generation Intel Core processors.

Process Technology

Westmere-based microprocessors and system on chips were manufactured on a 32 nm process ("P1268" for CPUs and "P1269" for SoCs). Intel's 32 nm process is second-generation high-K metal-gate transistors. Some of the modifications that took place from their 45 nm process is reduction in the thickness of the high-K layer from 1 nm to 0.9 nm.

+Westmere-based [[microprocessors]] and [[system on chips]] were manufactured on a [[32 nm process]] ("P1268" for CPUs and "P1269" for SoCs). Intel's 32 nm process is second-generation high-K metal-gate transistors. Some of the modifications that took place from their [[45 nm process]] is reduction in the thickness of the high-K layer from 1 nm to 0.9 nm.
