Core name

Intel Core i7 is a family of several Intel desktop and laptop 64-bit x86-64 processors, the first processors released using the Intel Nehalem microarchitecture and the successor to the Intel Core 2 family.[1][2][3][4] The Core i7 identifier applies to the initial family of processors[5][6] codenamed Bloomfield introduced in 2008 and the 2009 Lynnfield and Clarksfield models.[7] All current models are quad-core processors, but the upcoming Core i7-6xx "Arrandale" mobile processors only have two 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 already moved to the next generation 32 nm process.

Processor cores

Main articles: Bloomfield (microprocessor), Lynnfield (microprocessor), Clarksfield (microprocessor), and Arrandale (microprocessor)

The initial Core i7 processors released were codenamed Bloomfield branded as Core i7-9xx along with their Xeon 3500-series counterparts. As of 2009, they are Intel's high-end Desktop processors, sharing the Socket 1366 platform with the single and dual-processor server processors.

Lynnfield is the second processor sold under the Core i7 brand, while at the same time being sold as Core i5. Unlike Bloomfield, it does not have a QPI interface but directly connects to a southbridge using a 2.5 GT/s Direct Media Interface and to other devices using PCI Express links in its Socket 1156. Core i7 processors based on Lynnfield have Hyper-Threading, which is disabled in Lynnfield-based Core i5 processors.

Clarksfield is the mobile version of Lynnfield and available under the Core i7 Mobile brand, as part of the Calpella platform. It was released at the Intel Developer Forum on September 23, 2009[12]

The second mobile Core i7 processor family will be Arrandale, sold as the Core i7-6xx processors and featuring an integrated graphics processing unit but only two processor cores, half of Clarksfield. Clarkdale (microprocessor), the desktop version of Arrandale, will not be sold as Core i7, but only as Core i3 and Core i5.
