In March 2013, Apple released an updated version of the 3rd-generation Apple TV (Rev A, model A1469) containing a smaller, single-core version of the A5 processor. The 32 nm variant of the A5 provides around 15% better battery life during web browsing, 30% better when playing 3D games and about 20% better battery life during video playback. Markings on the square package indicate that it is named APL2498, and in software, the chip is called S5L8942.

The chip in the Apple TV has one core locked. Īn updated 32 nm version of the A5 processor was used in the 3rd-generation Apple TV, the fifth-generation iPod Touch, the iPad Mini, and the new version of iPad 2 (version iPad2,4). Like the A4, the A5 process size is 45 nm. The clock speed of the unit used in the iPhone 4S is 800 MHz. The iPad 2's technical specifications page says the A5 is clocked at 1 GHz, though it can adjust its frequency to save battery life. This GPU can push between 70 and 80 million polygons/second and has a pixel fill rate of 2 billion pixels/second. The A5 contains a dual-core ARM Cortex-A9 CPU with ARM's advanced SIMD extension, marketed as NEON, and a dual core PowerVR SGX543MP2 GPU. Compared to the A4, the A5 CPU 'can do twice the work' and the GPU has 'up to nine times the graphics performance', according to Apple. The chip commercially debuted with the release of Apple's iPad 2 tablet in March 2011, followed by its release in the iPhone 4S smartphone later that year. The Apple A5 is an SoC manufactured by Samsung that replaced the A4. To give the iPad high graphics bandwidth, the width of the RAM data bus is double that used in previous ARM11- and ARM9-based Apple devices. The RAM is connected to the processor using ARM's 64-bit-wide AMBA 3 AXI bus. The 1st-generation iPad, fourth-generation iPod Touch, and the 2nd-generation Apple TV have an A4 mounted with two low-power 128 MB DDR SDRAM chips (totaling 256 MB), while the iPhone 4 has two 256 MB packages for a total of 512 MB. The A4 processor package does not contain RAM, but supports PoP installation. Other performance improvements include additional L2 cache. The A4's SGX535 GPU could theoretically push 35 million polygons per second and 500 million pixels per second, although real-world performance may be considerably less. The A4 runs at different speeds in different products: 1 GHz in the first iPads, 800 MHz in the iPhone 4 and fourth-generation iPod Touch, and an undisclosed speed in the 2nd-generation Apple TV. The Cortex-A8 core used in the A4, dubbed ' Hummingbird', is thought to use performance improvements developed by Samsung in collaboration with chip designer Intrinsity, which was subsequently acquired by Apple It can run at far higher clock rates than other Cortex-A8 designs yet remains fully compatible with the design provided by ARM. The A4 commercially debuted in 2010, in Apple's iPad tablet, and was later used in the iPhone 4 smartphone, the fourth-generation iPod Touch, and the 2nd-generation Apple TV.

It combines an ARM Cortex-A8 CPU – also used in Samsung's S5PC110A01 SoC – and a PowerVR SGX 535 graphics processor (GPU), all built on Samsung's 45-nanometer silicon chip fabrication process. The Apple A4 is a PoP SoC manufactured by Samsung, the first SoC Apple designed in-house. 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.

The Apple 'A' series is a family of SoCs used in the iPhone, certain iPad models (iPads Pro and Air models released since 2021 use the M1 SoC), and the Apple TV.
