{{Use mdy dates|date=April 2015}}Apple Inc. has developed a range of "System on Chip" (SoC) as well as "System in Package" (SiP) processors for powering their mobile consumer devices and other tasks. To meet the stringent power and space constraints common to mobile devices, these chips combine a central processing unit (CPU) with other components into a single compact physical package. Johny Srouji is the executive in charge of Apple's silicon design.[1]

Early series

Prior to the introduction of the Apple "A" series of SoCs, Apple used several SoCs in early revisions of the iPhone and iPod touch. They were specified by Apple and manufactured by Samsung. They integrate a single ARM-based processing core (CPU), a graphics processing unit (GPU), and other electronics necessary to provide mobile computing functions within a single physical package.

The APL0098 (also 8900B[2] or S5L8900) is a package on package (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 ARM11 CPU and a PowerVR MBX Lite GPU. It was manufactured by Samsung on a 90 nm process.[3] The first generation iPod touch also used it.[3]

The APL0278[4] (also S5L8720) is a package on package (PoP) system on a chip (SoC) that was 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.[3][3]

The APL0298 (also S5L8920) is a package on package (PoP) system on a chip (SoC) that was introduced on June 8, 2009 at the launch of the iPhone 3GS. It includes a 600 MHz single-core Cortex-A8 CPU and a PowerVR SGX535 GPU. It was manufactured by Samsung on a 65 nm process.[8]

The APL2298 (also S5L8922) is a 45 nm die shrunk version of the iPhone 3GS SoC[3] and was introduced on September 9, 2009 at the launch of the third generation iPod touch.

Apple A4

{{Main|Apple A4}}

The Apple A4 is a package on package (PoP) system on a chip (SoC) designed by Apple Inc. and manufactured by Samsung.[5] It combines an ARM Cortex-A8 CPU with a PowerVR GPU, and emphasizes power efficiency.[6] The chip commercially debuted with the release of Apple's iPad tablet;[7] followed shortly by the iPhone 4 smartphone,[8] the 4th generation iPod touch and the 2nd generation Apple TV. It was superseded in the iPad 2, released the following year, by the Apple A5 processor.

Apple A4 is based on the ARM processor architecture.[9] The first version released ran at 1 GHz for the iPad[10] and contains an ARM Cortex-A8 CPU core paired with a PowerVR SGX 535 graphics processor (GPU)[7][11][12] built on Samsung's 45-nanometer (nm) silicon chip fabrication process.[13][14] The clock speed for the units used in the iPhone 4 and the iPod touch (4th generation) is 800 MHz. The clock speed for the unit used in the Apple TV has not been revealed.

The Cortex-A8 core used in the A4 is thought to use performance enhancements developed by chip designer Intrinsity, which was subsequently acquired by Apple,[15] in collaboration with Samsung.[16] The resulting core, dubbed "Hummingbird", is able to run at far higher clock rates than other implementations while remaining fully compatible with the Cortex-A8 design provided by ARM.[17] Other performance improvements include additional L2 cache. The same Cortex-A8 CPU core used in the A4 is also used in Samsung's S5PC110A01 SoC.[18][19] The SGX535 in the A4 could theoretically push 35 million polygons per second and 500 million pixels per second, although real world performance may be considerably less.[20]

The A4 processor package does not contain RAM, but supports PoP installation. Hence, there is a package with two low-power 128 MB DDR SDRAM chips (totaling 256 MB) mounted on top of the A4 used in the first-generation iPad, the fourth-generation iPod touch,[21] and the second-generation Apple TV.[22] The iPhone 4 has two 256 MB packages for a total of 512 MB.[23][24][25] The RAM is connected to the processor using ARM's 64-bit-wide AMBA 3 AXI bus. To support the iPad's demand for high graphics bandwidth, the width of the RAM data bus is double that used in previous ARM11 and ARM9 based Apple devices.[26]

Apple A5

{{Main|Apple A5}}

The Apple A5 is a system on a chip (SoC) designed by Apple Inc. and manufactured by Samsung[27] that replaced the A4. The chip commercially debuted with the release of Apple's iPad 2 tablet in March 2011,[28] followed by its release in the iPhone 4S smartphone later that year. Apple claims that compared with its predecessor, the A4, the A5 CPU "can do twice the work" and the GPU has "up to nine times the graphics performance".[29]

The A5 contains a dual-core ARM Cortex-A9 CPU[30] with ARM's advanced SIMD extension, marketed as NEON, and a dual core PowerVR SGX543MP2 GPU. This GPU can push between 70 and 80 million polygons/second and has a pixel fill rate of 2 billion pixels/second. Apple lists the A5 to be clocked at 1 GHz on the iPad 2's technical specifications page,[31] though it can dynamically adjust its frequency to save battery life.[30][32] The clock speed of the unit used in the iPhone 4S is 800 MHz. Like the A4, the A5 process size is 45 nm.[33]

An updated 32 nm version of the A5 processor was used in the third generation Apple TV, the iPod touch (5th generation), the iPad Mini, and the new version of iPad 2 (version iPad2,4).[34] The chip in the Apple TV has one core locked.[35][36] The markings of the square package indicates that it is named APL2498, and in software, the chip is called S5L8942. The 32 nm variant of the A5 provides around 15% better battery life during web browsing, 30% better when playing 3D games and approximately 20% better battery life during video playback.[37]

In March 2013, Apple released an updated version of the third generation Apple TV (AppleTV3,2) containing a smaller, single-core version of the A5 processor. Unlike the other A5 variants, this version of the A5 is not a package-on-package (PoP), having no stacked RAM. The chip is very small, just 6.1×6.2 mm, but as the decrease in size is not due to a decrease in feature size (it is still on a 32 nm fabrication process), this indicates that this A5 revision is of a new design.[38] Markings tell that it is named APL7498, and in software, the chip is called S5L8947.[39][40]

Apple A5X

{{Main|Apple A5X}}

The Apple A5X is a system-on-a-chip (SoC) designed by Apple Inc. that was announced on March 7, 2012, at the launch of the third generation iPad. It is a high performance variant of the Apple A5; Apple claims it has twice the graphics performance of the A5.[41] It was superseded in the fourth generation iPad by the Apple A6X processor.

This SoC has a quad-core graphics unit (PowerVR SGX543MP4) instead of the previous dual-core as well as a quad-channel memory controller that provides a memory bandwidth of 12.8 GB/s, roughly three times more than in the A5. The added graphics cores and extra memory channels add up to a very large die size of 165 mm²,[42] for example twice the size of Nvidia Tegra 3.[43] This is mainly due to the large PowerVR SGX543MP4 GPU. The clock frequency of the dual ARM Cortex-A9 cores have been shown to operate at the same 1 GHz frequency as in A5.[44] The RAM in A5X is separate from the main CPU package.[45]

Apple A6

{{Main|Apple A6}}

The Apple A6 is a package on package (PoP) system on a chip (SoC) designed by Apple that was introduced on September 12, 2012, at the launch of the iPhone 5, then a year later was inherited by its minor successor the iPhone 5C. Apple states that it is up to twice as fast and has up to twice the graphics power compared to its predecessor the Apple A5.[46] It is 22% smaller and draws less power than the 45 nm A5.[47]

The A6 is said to use a 1.3 GHz[48] custom[57] Apple-designed ARMv7 based dual-core CPU, called Swift,[49] rather than a licensed CPU from ARM like in previous designs, and an integrated 266 MHz triple-core PowerVR SGX 543MP3[50] graphics processing unit (GPU). The Swift core in the A6 uses a new tweaked instruction set, ARMv7s, featuring some elements of the ARM Cortex-A15 such as support for the Advanced SIMD v2, and VFPv4.[57] The A6 is manufactured by Samsung on a high-κ metal gate (HKMG) 32 nm process.[51]

Apple A6X

{{Main|Apple A6X}}Apple A6X is a 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.[52]

Like the A6, this SoC continues to use the dual-core Swift CPU, but it has a new quad core GPU, quad channel memory and slightly higher 1.4 GHz CPU clock rate.[53] It uses an integrated quad-core PowerVR SGX 554MP4 graphics processing unit (GPU) running at 300 MHz and a quad-channel memory subsystem.[53][54] Compared to the A6 the A6X is 30% larger, but it continues to be manufactured by Samsung on a high-κ metal gate (HKMG) 32 nm process.[54]

Its first appearance was in the iPhone 6 and iPhone 6 Plus, which were introduced on September 9, 2014.[64] A year later it would drive the iPad Mini 4. Apple states that it has 25% more CPU performance and 50% more graphics performance while drawing only 50% of the power compared to its predecessor, the Apple A7.[65] On February 9, 2018 Apple released the HomePod, which is powered by an Apple A8 with 1 GB of RAM.[66]

The A8 features an Apple-designed 1.4[83] GHz 64-bit[84] ARMv8-A[84] dual-core CPU, and an integrated PowerVR GX6450 GPU in a four cluster configuration.[83] The A8 is manufactured on a 20 nm process[67] by TSMC,[68] which replaced Samsung as the manufacturer of Apple's mobile device processors. It contains 2 billion transistors. Despite that being double the number of transistors compared to the A7, its physical size has been reduced by 13% to 89 mm2 (consistent with a shrink only, not known to be a new microarchitecture).[69]
