The first Intel processors to be built using 32nm technology are codenamed Westmere and will be a die-shrink of the current Nehalem architecture, but the smaller process technology will also free up room on the package to integrate a 45nm graphics and memory controller on a separate die. The initial chips will target mainstream mobile and desktop systems, and were demonstrated by Intel at an event in San Francisco today.
The chipmaker also said that its 32nm process will be split into two versions, one optimized for mainstream chips and one for system-on-a-chip (SoC) processors aimed at netbooks and other mobile devices. All of this, however, will be preceded by 45nm quad-core Nehalem parts codenamed Lynnfield and Clarksfield that target mainstream desktop and laptops respectively.
