Nehalem microarchitecture based

Nehalem microarchitecture basedMain article:Nehalem (microarchitecture)With theNehalem microarchitecture[14], Intel introduced a new naming scheme for its Core processors. There are three variants, Core i3, Core i5, and Core i7, but the names no longer correspond to specific technical features like the number of cores. Instead, the brand is now divided from low-level (i3), through mid-range (i5) to high-end performance (i7)[15], which correspond to three to five stars in IntelsIntel Processor Ratingas opposed to the entry-level Celeron (one star) and Pentium (two stars) processors.[16]. Common features of all Nehalem based processors include an integrated DDR3 memory controller as well asQuickPath InterconnectorPCI ExpressandDirect Media Interfaceon the processor replacing the aging quad-pumpedFront Side Busused in all earlier Core processors. Also, all these processors have 256 KB L2 cache per core, plus up to 12 MiB shared level 3 cache. Because of the new I/O interconnect, chipsets and mainboards from previous generations can no longer be used with Nehalem based processors.

[edit]Core i3The Core i3 was intended to be the new low end of the performance processor line from Intel, following the retirement of theCore 2brand.[17]

HYPERLINK "http://en.wikipedia.org/wiki/Intel_Core" \l "cite_note-17#cite_note-17" [18]The first Core i3 processors were launched on January 7, 2010.[19]The first Nehalem based Core i3 wasClarkdale-based, with an integratedGPUand two cores.[20]The same processor is also available as Core i5 and Pentium, with slightly different configurations.

The Core i3-3xxM processors are based onArrandale, the mobile version of the Clarkdale desktop processor. They are similar to the Core i5-4xx series but running at lower clock speeds and withoutTurbo Boost.[21]Codename(main article)Brand name (list)L3 CacheSocketTDPI/O Bus

[edit]Core i5Main article:Intel Core i5Core i5[22], like Core i7, is based on theNehalemmicroarchitecture. The first Core i5 was introduced on September 8, 2009 and is a mainstream variant of the Core i7, initially only quad-core desktop processors based onLynnfield, with dual-core mobile (Arrandale) and desktop processors (Clarkdale) following in 2010.

[edit]Core i7Main article:Intel Core i7As of 2010,Core i7is the high end of the Core brand[23], which was introduced with theBloomfieldQuad-core processor in late 2008. In 2009, new Core i7 models based on theLynnfielddesktop quad-core processor and theClarksfieldquad-core mobile were added, and models based on theArrandaledual-core mobile processor have been announced. The first six-core processor in the Core lineup is theGulftown, which was launched on March 16, 2010. Both the regular Core i7 and theExtreme Editionare advertised as five stars in theIntel Processor Rating.
