What is Intel Core i5?
[[File:Intel Core i5 750 1.jpg|thumb|right|250px|{{Center| Intel Core i5 [[microprocessor]]}}]] '''Intel Core i5''' is a name that [[Intel]] uses for the computer [[processor]]s it makes for [[Computer#Kinds_of_computers|desktop]] and [[Computer#Kinds_of_computers|laptop]] computers. The first '''Core i5''' is a [[wikt:version|version]] of the earlier [[Intel Core i7|Core i7]], the Lynnfield core.<ref>{{Citation |title=Intel's Core i7 870 & i5 750, Lynnfield: Harder, Better, Faster Stronger |url=http://anandtech.com/cpuchipsets/showdoc.aspx?i=3634 |author=Anand Lal Shimpi |publisher=anandtech.com}}</ref> Lynnfield Core i5 processors have an 8 MB L3 [[cache]]. They have a DMI ([[Direct Media Interface]]) bus running at 2.5 GT/s. Core i5 also has support for dual-channel [[DDR SDRAM]] memory and have Hyper-threading disabled. A new feature called [[Turbo Boost Technology]] was introduced which maximizes speed for demanding [[computer program]]s. This increases [[Speed|performance]] to match the amount of work the computer must do. The Core i5-5xx [[mobile processor]]s are named [[Arrandale]].<ref>{{cite web |url=http://www.tomshardware.com/reviews/mobile-core-i5-arrandale,2522.html |title=Intel's Mobile Core i5 And Core i3: Arrandale Is For The Rest Of Us |author=Chris Angelini|date=2 January 2010 |website= |publisher=Tom's Hardware Guide ™ |accessdate=8 January 2015}}</ref> They are based on the 32nm Westmere shrink of the Nehalem [[microarchitecture]].
