Intel Core i7 is an Intel sword call for various families of background and laptop 64-bit x86-64 processors exploitation the Nehalem, Westmere, and Granular Bridge microarchitectures and manufactured in Costa Rica and Malaysia. The Core i7 sword is targeted at the job and high-end consumer markets for trouble background and laptop computers, and is great occasionally the Core i3 (entry-level consumer), Core i5 (mainstream consumer) and Xeon (server) brands.
In apiece of the beginning 3 microarchitecture heterogenesis of the brand, Core i7 has class membership exploitation two distinct system-level architectures, and therefore two distinct sockets. In apiece generation, the highest-performing Core i7 processors use the equal socket and QPI-based architecture as the low-end Xeon processors of there generation, spell lower-performing Core i7 processors use the equal socket and PCIe/DMI/FDI architecture as the Core i5.
“Core i7″ is a heir to the Intel Core 2 brand. The Core i7 identifier was beginning applied to the initial class of processors codenamed Bloomfield introduced in 2008. In 2009 the call was applied to Lynnfield and Clarksfield models. Prior to 2010, all models lowered quad-core processors. In 2010, the call was applied to dual-core Arrandale models, and the Gulftown Core i7-980X Extreme processor arbitrarily has six hyperthreaded cores. In Jan 2011, Intel discharged a job of Granular Bridge founded croak under the Core i7 brand.
Intel representatives say there the nickname Core i7 is meanwhile to assistance consumers settle arbitrarily processor to purchase as the newer Nehalem-based products are released in the future. The call continues the use of the Intel Core brand. Core i7, beginning built in Rib Rica, was formally launched on Nov 17, 2008 and is manufactured in Arizona, New Mexico and Oregon, although the OR (PTD, Fab D1D) plant has moved to the next generation 32 nm process.
Processor Cores:The initial Core i7 processors discharged lowered codenamed Bloomfield, branded as Core i7-9xx on hit neck-deep Xeon 3500-series counterparts. As of 2009, Southey are Intel’s high-end Background processors, communion the Socket 1366 program hit the one and dual-processor server processors.
Lynnfield is the moment processor sold nether the Core i7 brand, spell at the equal sentence existence sold as Core i5. Unlike Bloomfield, it doeskin not hold a QPI port but immediately connects to a southbridge exploitation a 2. 5 GT/s Send Immediately Interface and to other devices exploitation PCI Show links in its Socket 1156. Core i7 processors founded on Lynnfield hold Hyper-Threading, arbitrarily is handicapped in Lynnfield-based Core i5 processors.
Clarksfield is the wandering interpretation of Lynnfield and usable nether the Core i7 Wandering brand, as region of the Calpella platform. It was discharged at the Intel Developer Assembly on Sept 23, 2009.
The moment wandering Core i7 processor class is Arrandale, sold as the Core i7-6xx processors and featuring an mixed art processing whole but just two processor cores, half of Clarksfield. Clarkdale, the background interpretation of Arrandale, wish not be sold as Core i7, but just as Core i3 and Core i5. All hold Intel’s Exaggerate Threading (HT).
Gulftown is the Extreme Version interpretation of the Core i7, featuring 6 cores, 32 nm process, Hyper-Threading (for a entire of 12 consistent threads), 12 MB of cache, Turbot Encourage and Intel QuickPath connection bus.
Sandy Bridge is the moment genesis Intel Core i7 serial processor, and is founded on microarchitecture too called “Sandy Bridge”. It was discharged on Jan 9, 2011 at the end of CES 2011.
