Introduced in March 2012 and branded simply as "the new iPad," the iPad (Retina) improved on the iPad 2 in several areas, most prominiantly the screen: it included a stunning high-resolution "retina" display which doubled the resolution of the iPad 2. As with the introduction of "retina" graphics in the iPhone 4, the new iPad's doubled resolution allowed an easy transition for app developers; most text was automatically rendered at the higher-resolution, and other graphics were simply pixel-doubled.

The iPad (Retina) included the Apple-designed A5X processor, which improved on the A5 primarily with the inclusion of a faster, quad-core graphics chipset. The new iPad also included twice the RAM of the iPad 2, an upgraded 5 mega-pixels rear-facing camera, and support for 4G LTE on the cellular models (an Apple first). Dictation support was added (via iOS 5.1), but the iPhone 4S's "Siri" feature was not included.

The iPad (Retina) maintained the same storage capacity and price points of the iPad 2:

  • 16 GB: $499
  • 32 GB: $599
  • 64 GB: $699

AT&T or Verizon 4G LTE models were available at a $130 premium, and were limited to 3G internationally.
