| − | '''Westmere''' ('''WSM''') 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 {{intel|Core}} processors.

| − | 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. The process shrink enjoyed a roughly 0.7x scaling compared to the [[45 nm process]] for the gate pitch and metal 1 interconnect.
