Apple has released five different iPads as of the time of publication: the original iPad in 2010; the iPad 2 in 2011; the new iPad, known unofficially as the iPad 3, in 2012; the iPad Mini in 2012 and the iPad with Retina display, known unofficially as the iPad 4, in 2012. Both the original iPad and the iPad 3 have been discontinued by Apple but can be bought secondhand from other suppliers. The processor, which is the component that physically carries out the calculations needed to perform computing tasks, varies across the range. Although the processor speed has only increased slightly during the iPad’s history, other factors mean performance feels faster in later models. Writer Bio
