The Apple A6X is a 32-bit system-on-a-chip (SoC) designed by Apple Inc., introduced at the launch of the fourth generation iPad on October 23, 2012. It is a high-performance variant of the Apple A6. Apple claims the A6X has twice the CPU performance and up to twice the graphics performance of its predecessor, the Apple A5X.

Design
The A6X features a 1.4 GHz custom Apple-designed ARMv7-A based dual-core CPU called Swift, introduced in the Apple A6. It includes an integrated quad-core PowerVR SGX554MP4 graphics processing unit (GPU) running at 300 MHz and a quad-channel memory subsystem. The memory subsystem supports LPDDR2-1066 DRAM, increasing the theoretical memory bandwidth to 17 GB/s.
Unlike the A6, but similar to the A5X, the A6X is covered with a metal heat spreader, includes no RAM, and is not a 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.
