<P> There have been eight versions of the iPad . The first generation established design precedents , some of which , such as the home button placement , have persisted through all models . The 2nd - generation iPad ( iPad 2 ) introduced a new thinner design , a dual - core Apple A5 processor , and VGA front - facing and 720p rear - facing cameras designed for FaceTime video calling . The third generation added a Retina Display , the new Apple A5X processor with a quad - core graphics processor , a 5 - megapixel camera , HD 1080p video recording , voice dictation , and 4G ( LTE ) . The fourth generation added the Apple A6X processor and replaced the 30 - pin connector with an all - digital Lightning connector . The iPad Air added the Apple A7 processor and the Apple M7 motion coprocessor , and reduced the thickness for the first time since the iPad 2 . The iPad Air 2 added the Apple A8X processor , the Apple M8 motion coprocessor , an 8 - megapixel camera , and the Touch ID fingerprint sensor ; and further reduced the thickness . The iPad introduced in 2017 added the Apple A9 processor , while sacrificing some of the improvements the iPad Air 2 introduced in exchange for a lower launch price . </P>
