Core 2 is an eighth-generation x86 architecture microprocessor produced by Intel and based on the Intel Core microarchitecture. Core 2 was to mark the retirement of Intel's Pentium brand name that had been used since 1993 (although in early 2007, laptops carrying an "Intel Pentium Dual Core" label began appearing with no explanation from Intel other than to say it is not a Pentium D). Core 2 saw the reunion of Intel's notebook and desktop product lines since Pentium M and Pentium 4 in 2003. The first wave of Core 2 processors was officially released on July 27, 2006. Like the Intel Core brand that it supersedes, Core 2 currently offers Duo (dual-core) processors, but also Quad (four-core) models, with an Extreme (high-end) model. The base processors are code-named "Conroe" (for desktop use) and "Merom" (for portable use); their variants have code names such as "Kentsfield" (quad-core Conroe) and "Penryn" (45 nm Merom). Although the "Woodcrest" server CPUs are also based on Core microarchitecture...........
