List of Apple processors

Apple Inc. designs its own (SoC) and  (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, Israel.

History
In April 2008, Apple acquired P.A. Semi for $278 million to bring 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.

Early processors
Apple first used SoC 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 APL0098 (also 8900B or S5L8900) is a (PoP) system on a chip (SoC) that was introduced on June 29, 2007, at the launch of the original iPhone. It includes a 412 MHz single-core  CPU and a  MBX Lite GPU. It was manufactured by Samsung on a 90 nm . The iPhone 3G and the 1st-generation iPod touch also used it.
 * The APL0278 (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.
 * 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 CPU and a PowerVR SGX535 GPU. It was manufactured by Samsung on a 65 nm process.
 * The APL2298 (also S5L8922) is a 45 nm version of the iPhone 3GS SoC and was introduced on September 9, 2009, at the launch of the 3rd-generation iPod touch.

A series
The Apple A series is a family of 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), 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.
 * Apple A4 — introduced in the original iPad and also used in the iPhone 4, iPod touch (4th generation), and Apple TV (2nd generation).
 * Apple A5 — introduced in the iPad 2 and used in the iPhone 4S, iPod touch (5th generation) and 1st generation iPad mini.
 * Apple A5X — introduced in the iPad (3rd generation).
 * Apple A6 — introduced in the iPhone 5 and later used in the iPhone 5C; contained a custom CPU designed internally at Apple (called "Swift") instead of one licensed from ARM.
 * Apple A6X — introduced in the iPad (4th generation).
 * Apple A7 — introduced in the iPhone 5S, the company's first 64-bit mobile processor. Also used in the 2nd and 3rd generation iPad minis and 1st generation iPad Air.
 * Apple A8 — introduced in the iPhone 6 and 6 Plus; also used by the iPad mini 4, 6th generation iPod touch, and the HomePod.
 * Apple A8X — introduced in the iPad Air 2.
 * Apple A9 — introduced in the iPhone 6S and 6S Plus, and later used in the 1st-generation iPhone SE and the 5th-generation iPad.
 * Apple A9X — introduced in the 1st-generation iPad Pro, the company's first "desktop class" processor for mobile devices.
 * Apple A10 Fusion — introduced in the iPhone 7 and 7 Plus, and later used in the 6th and 7th-generation iPad. This was the first processor produced for Apple solely by TSMC.
 * Apple A10X Fusion — introduced in the 2nd-generation iPad Pro, and also used in the 1st-generation Apple TV 4K.
 * Apple A11 Bionic — introduced in the iPhone 8, 8 Plus, and iPhone X. First implementation of Neural Engine machine learning.
 * Apple A12 Bionic — introduced in the iPhone XR, XS, and XS Max, and also used in the 3rd-generation iPad Air, 5th-generation iPad mini and the 2nd-generation Apple TV 4K, and later used in the 8th-generation iPad.
 * Apple A12X Bionic — introduced in the 3rd-generation iPad Pro.
 * Apple A12Z Bionic — introduced in the 4th-generation iPad Pro, and used in the 2020 Mac mini-based Developer Transition Kit.
 * Apple A13 Bionic — introduced in the iPhone 11, 11 Pro, 11 Pro Max; also used in the 2nd-generation iPhone SE, and later used in the 9th-generation iPad.
 * Apple A14 Bionic — introduced in the 4th-generation iPad Air and also used in the iPhone 12 series.
 * Apple A15 Bionic — introduced in the iPhone 13 series and the 6th-generation iPad mini.

M series
Introduced by Apple in late 2020 to transition its Mac computers away from Intel processors. By the end of following year, only three Intel-based Macs remained: the 27-inch iMac, the Mac mini (still offered as an alternative to the M1 version), and the 3rd-generation Mac Pro.
 * Apple M1 — introduced in November 2020 with support for up to 16 GB RAM for the first Apple Silicon-based Macs, the MacBook Air, 13-inch MacBook Pro, and Mac mini; also adopted by the 24-inch iMac and 5th-generation iPad Pro in April 2021.
 * Apple M1 Pro — introduced in October 2021 with support for up to 32 GB RAM for the 14 and 16-inch MacBook Pros.
 * Apple M1 Max — introduced in October 2021 with support for up to 64 GB RAM for the 14 and 16-inch MacBook Pros.

M series (motion coprocessors)

 * 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 (Apple M9, M10, M11) were integrated on the die of subsequent Apple processors, starting with the Apple A9. For more information, see Apple motion coprocessors.
