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.[1] It was introduced with and only used in the iPad Air 2, which was announced on October 16, 2014.[7] 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.[7][8] The latest software update for the iPad Air 2 using this chip is iPadOS 15.8.3, released on March 5, 2024, as it was discontinued with the release of iPadOS 16 in 2022 due to hardware limitations of the A8X.
