The Apple A6X is a

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.

Design

The A6X features a 1.4 GHz custom Apple-designed

ARMv7-A architecture based dual-core CPU called Swift,[1] introduced in the Apple A6.[7] It includes an integrated quad-core PowerVR SGX554MP4 graphics processing unit (GPU)[1] running at 300 MHz[citation needed] and a quad-channel memory subsystem.[1] The memory subsystem supports LPDDR2-1066 DRAM, increasing the theoretical memory bandwidth to 17 GB/s.[3]

Unlike the

package-on-package (PoP) assembly. The A6X is manufactured by Samsung on a High-κ metal gate (HKMG) 32 nm process. It has a die with an area of 123 mm2, 30% larger than the A6.[4]
