Johny Srouji at Apple's chip facilities in Cupertino.

Apple Inc. designs its own system on a chip (SoC) and system in package (SiP) processors for its consumer devices. Marketed as "Apple Silicon", development is headed by Senior VP of Hardware Technologies Johny Srouji at Apple's chip facilities in Cupertino, California and Herzliya, Israel.[1][2]

In April 2008, Apple acquired P.A. Semi for $278 million to bring fabless processor design in-house to the company. At the time, Apple relied on Intel for central processing units in its desktop products and Samsung for its mobile products.[3]

Early processors

Apple first used SoC (system on a chip) designs in early revisions of the iPhone and iPod touch. Specified by Apple and manufactured by Samsung, they combine into one package: a single ARM-based processing core (CPU), a graphics processing unit (GPU), and other electronics necessary for mobile computing.

  • The APL0278[7] (also S5L8720) is a PoP SoC introduced on September 9, 2008, at the launch of the second-generation iPod touch. It includes a 533 MHz single-core ARM11 CPU and a PowerVR MBX Lite GPU. It was manufactured by Samsung on a 65 nm process.[5][6]
  • The APL0298 (also S5L8920) is a PoP SoC introduced on June 8, 2009, at the launch of the iPhone 3GS. It includes a 600 MHz single-core ARM Cortex-A8 CPU and a PowerVR SGX535 GPU. It was manufactured by Samsung on a 65 nm process.[8]

A series

The Apple A series is a family of SoC designs developed by Apple for use in their mobile and consumer devices. They integrate one or more ARM-based processing cores (CPU), a graphics processing unit (GPU), cache memory and other electronics necessary to provide mobile computing functions within a single physical package. These were originally manufactured for Apple by Samsung, but production has since shifted to TSMC.[9]

  • Apple M7 — introduced with the Apple A7 in the iPhone 5S in September 2013.
  • Apple M8 — introduced with the Apple A8 in the iPhone 6 and 6 Plus in September 2014.
Later versions were integrated on the die of subsequent Apple processors, starting with the A9. For more information, see List of Apple motion coprocessors.
