The Apple A6X is a 32-bit system-on-a-chip (SoC) designed by Apple Inc., part of the Apple silicon series. It was introduced with and only used in the 4th generation iPad, on October 23, 2012. It is a high-performance variant of the Apple A6 and the last 32-bit chip Apple used on an iOS device before Apple switched to 64-bit. Apple claims the A6X has twice the CPU performance and up to twice the graphics performance of its predecessor, the Apple A5X.[6] Software updates for the 4th generation iPad ended in 2019 with the release of iOS 10.3.4 for cellular models, thus ceasing support for this chip as it was discontinued with the release of iOS 11 in 2017.
