“Over a year ago at the Fall 2005 Intel Developer Forum, Intel formally announced that they would be dropping the Pentium 4’s Netburst microarchitecture in favor of a brand new, more power-efficient microarchitecture that would carry the company’s entire x86 product line, from laptops up through Xeon servers, into the next decade. This past IDF saw the unveiling of some significant details about this new microarchitecture, ‘Merom’ or ‘Core’. Intel presented many of these details in a presentation on Core, and others were obtained by David Kanter of Real World Technologies. The present article draws on both of those sources, as well as my own correspondence with Intel, to paint what is (hopefully) an accessible picture of the new microarchitecture that will soon be powering everything from Windows Vista servers to Apple laptops.”
Into the Core: Intel’s Next-Generation Microarchitecture

Before any reads this and rushes out to get a Mac, it’s important to note that the Core Solo and Core Duo processors do not use the Intel Core Microarchitecture, they use a modified version of Pentium M (code-named “Yonah”). This chip does not have the macro-fusion, wide bus, EMT64, or genuine 128-bit SSE features.
The laptop chip code-named “Merom” will be the first genuine Core architected chip released, followed shortly by Conroe for the desktop. These will still, apparently, be known as Core Solo and Duo (and possibly Quatro in Q1-2007), but will have different part numbers
