Intel Core 2 was a processor family encompassing a range of Intel's mainstream 64-bit x86-64 single-, dual-, and quad-core microprocessors based on the Core microarchitecture. The single- and dual-core models are single-die, whereas the quad-core models comprise two dies, each containing two cores, packaged in a multi-chip module.[2] The Core 2 range was the last flagship range of Intel desktop processors to use a front-side bus (FSB).

The introduction of Core 2 relegated the Pentium brand to the mid-range market, and reunified laptop and desktop CPU lines for marketing purposes under the same product name, which were formerly divided into the Pentium 4, Pentium D, and Core Solo/Duo brands.

The Core 2 processor line was introduced on July 27, 2006,[3] comprising the Duo (dual-core) and Extreme (dual- or quad-core CPUs for enthusiasts), and in 2007, the Quad (quad-core) and Solo (single-core) sub-brands.[4] Intel Core 2 processors with vPro technology (designed for businesses) include the dual-core and quad-core branches.[5]

Although Woodcrest processors are also based on the Core 2 architecture, they are available under the Xeon brand. From December 2006, all Core 2 processors were manufactured from 300-millimeter plates at Fab 12 factory in Arizona and at Fab 24-2 in County Kildare, Ireland.
