The new Intel Core microarchitecture, which was unveiled during IDF Spring 2006, will be used on all new CPUs from Intel, like Merom, Conroe and Woodcrest. It is based on Pentium M’s microarchitecture, bringing some new features. In this tutorial we will give you an in-depth trip into this new microarchitecture from Intel.
The first thing to have in mind is that, besides the name, Core microarchitecture has nothing to do with Intel’s Core Solo and Core Duo CPUs. Core Single is a Pentium M manufactured under 65 nm technology, while Core Duo – formerly known as Yonah – is a dual-core 65 nm CPU based on Pentium M’s microarchitecture.
Pentium M is based on Intel’s 6th generation architecture, a.k.a. P6, the same used by Pentium Pro, Pentium II, Pentium III and early Celeron CPUs and not on Pentium 4’s as you may think, being originally targeted to mobile computers. You may think of Pentium M as an enhanced Pentium III. Thus you may think of Core microarchitecture as an enhanced Pentium M.
