Apple A6X is a 32-bit system-on-a-chip (SoC) designed by Apple, 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.[5]

Design

The A6X features a 1.4 GHz custom Apple-designed ARMv7-A based dual-core CPU called Swift,[1] introduced in the Apple A6.[6] 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 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.[4]
