Nehalem

From Mac Guides

Nehalem is a processor microarchitecture that is being developed by Intel and is the planned successor to Penryn. Intel is already into the development process for Nehalem. Nehalem uses the 45nm manufacturing methods from Penryn and applies it to the new Nehalem microarchitecture. This processor should debut in 2008 and very little else is known about it.

Westmere, formally Nehalem-C [1] is also based on the Nehalem microarchitecture and will be a die shrink from 45nm to 32nm. Westmere should be ready for a 2009 release providing that Intel stays on target with its roadmap.
