Intel Core 2
Core 2 is a brand encompassing a range of Intel's consumer 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 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 previously had been divided into the Pentium 4, Pentium D, and Pentium M brands.

The Core 2 brand 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) subbrands.[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 architecture, they are available under the Xeon brand. From December 2006, all Core 2 Duo processors were manufactured from 300 millimeter plates at Fab 12 factory in Arizona and at Fab 24-2 in County Kildare, Ireland.
Models
The Core 2-branded CPUs include: "Conroe"/"Allendale" (dual-core for desktops), "Merom" (dual-core for laptops), "Merom-L" (single-core for laptops), "Kentsfield" (quad-core for desktops), and the updated variants named "Wolfdale" (dual-core for desktops), "Penryn" (dual-core for laptops), and "Yorkfield" (quad-core for desktops).[lower-alpha 1]
The Core 2 branded processors feature Virtualization Technology (with some exceptions), Execute Disable Bit, and SSE3. Their Core microarchitecture introduced SSSE3, Trusted Execution Technology, Enhanced SpeedStep, and Active Management Technology (iAMT2). With a maximum thermal design power (TDP) of 65W, the Core 2 Duo Conroe dissipates half the power of the less capable contemporary Pentium D-branded desktop chips[7] that have a max TDP of 130 W.[8]

List of Intel Core 2 microprocessors |
With the release of the Core 2 processor, the abbreviation C2 has come into common use, with its variants C2D (the present Core 2 Duo), and C2Q, C2E to refer to the Core 2 Quad and Core 2 Extreme processors respectively. C2QX stands for the Extreme-Editions of the Quad (QX6700, QX6800, QX6850).
The successors to the Core 2 brand are a set of Nehalem microarchitecture based processors called Core i3, i5, and i7. Core i7 was officially launched on November 17, 2008 as a family of three quad-core processor desktop models, further models started appearing throughout 2009. The last Core 2 processor to be released was the Core 2 Quad Q9500 in January 2010. The Core 2 processor line was removed from the official price lists in July 2011,[9][10] and the last processors were discontinued in June 2012.[1]
