i7 processor

Intel Core i7 is an Intel brand name for several families of desktop and laptop 64-bit x86-64 processors using the Nehalem, Westmere, and upcoming Sandy Bridge microarchitectures. The "Core i7" brand is marketed for the business and high-end consumer markets and is intended to differentiate these processors from Core i5 processors intended for the main-stream consumer market and Core i3 processors intended for the entry-level consumer market.
"Core i7" is a successor to the Intel Core 2 brand.^[1][2][3][4] The Core i7 identifier was first applied to the initial family of processors^[5][6] codenamed Bloomfield introduced in 2008. In 2009 the name was applied to Lynnfield and Clarksfield models.^[7] Prior to 2010, all models were quad-core processors. In 2010, the name was applied to dual-core Arrandale models, and the Gulftown Core i7-980X Extreme processor which has six hyperthreaded cores.

Intel representatives state that the moniker Core i7 is meant to help consumers decide which processor to purchase as the newer Nehalem-based products are released in the future.^[8] The name continues the use of the Intel Core brand.^[9] Core i7, first assembled in Costa Rica,^[10] was officially launched on November 17, 2008^[11] and is manufactured in Arizona, New Mexico and Oregon, though the Oregon (PTD, Fab D1D) plant has moved to the next generation 32 nm process.
