The fourth-generation iPad, sold as the iPad with Retina display and commonly called the iPad 4, is a full‑size tablet computer produced by Apple. Introduced in October 2012 as an update to the previous Retina iPad, it maintained the same industrial design and high‑resolution 9.7‑inch Retina display while updating internal components and the device connector. Apple presented this model as an incremental refresh emphasizing faster performance and a change in the accessory interface. For the original product information, see the official overview: Apple product page.

Key characteristics

The iPad 4 combined the established Retina-class display with a new system-on-chip and a new physical connector. Its principal changes were intended to improve app responsiveness, graphics performance and compatibility with newer accessories.

  • Display: 9.7‑inch Retina display with high pixel density designed for reading, photos and video.
  • Processor and performance: Apple A6X system‑on‑chip, providing noticeable gains in CPU and GPU performance over the previous model in tasks such as gaming and media playback.
  • Connector and accessories: Replaced the older 30‑pin dock connector with the smaller Lightning connector, prompting adapters and updated accessories.
  • Connectivity: Standard Wi‑Fi models and optional cellular variants with support for mobile broadband technologies available at the time.
  • Software: Shipped with iOS 6 and was supported through subsequent iOS updates during its active lifecycle; for historical update notes see iOS release notes.

History and reception

The iPad 4 arrived quickly after its predecessor, reflecting Apple's cadence of timely internal upgrades. Contemporary reviews noted the improved speed and graphics as the most significant practical benefits, while the switch to Lightning attracted attention because it altered compatibility with many existing accessories and docks.

Uses and significance

In use, the iPad 4 served the same broad roles as other full‑size iPads: web browsing, video and music consumption, gaming, education and lighter productivity. The enhanced graphics performance made it a better fit for graphically demanding apps and improved media playback. Its familiarity of form factor and display kept it compatible with many existing cases and stands that matched the Retina‑screen iPad lineage.

Compatibility, accessories and legacy

The Lightning connector required many accessory makers to revise designs or provide adapters to maintain backward compatibility with older 30‑pin peripherals. Apple and third parties sold compatible adapters and updated docks to ease the transition; for guidance and accessory options see accessory resources: adapters and accessories and official support documentation: support articles. The iPad 4 was succeeded the following year by a redesigned, thinner model that began a new generation of iPad designs, but it remains notable for introducing Lightning to Apple’s tablet lineup and for delivering a clear performance uplift within the Retina iPad family.
