The Apple A8X is a 64-bit ARM-based system on a chip (SoC) designed by Apple Inc., part of the Apple silicon series, and manufactured by TSMC. It was introduced with and only used in the iPad Air 2, which was announced on October 16, 2014. It is a variant of the A8 inside the iPhone 6 family of smartphones and Apple states that it has 40% more CPU performance and 2.5 times the graphics performance of its predecessor, the Apple A7.
The latest software update for the iPad Air 2 using this chip is iPadOS 15.8.4 (updated on March 31, 2025), as the hardware limitations of the A8X meant it could not update with the release of iPadOS 16 in 2022.
