Apple promoted the 4G iPad as having twice the performance, faster WiFi, and a new FaceTime HD camera. It was the first iPad with a Lightning connector, introduced with the iPhone 5 earlier in the year, and had improved 4G LTE support compared to the 3G iPad.

The 4G iPad is built around Apple’s A6X processor with quad-core graphics, and it runs at an impressive 1.4 GHz – 40% faster than any previous iPad. Benchmarks supported Apple’s claim that the 4G iPad has twice the processing power of the 3G iPad.

In fact, Geekbench results show the 4G iPad has nearly 3x the processing power of the iPad 2 and 3G iPad.

In February 2013, it became the first iPad with a 128 GB option.

The 4G iPad was the first to come back from the dead. It was discontinued with the introduction of the iPad Air on October 22, 2013 while the iPad 2 continued on as Apple’s entry-level 9.7″ iPad. The 4G iPad returned on March 18, 2014, when the iPad 2 was phased out. It was again discontinued in October 2014, leaving the line with only iPad Air and iPad mini models.
