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 certain models of the iPhone, iPad (latest iPads Pro and Air use the Apple M1 SoC), iPod Touch, the discontinued original HomePod, and the Apple TV digital media player. The APL2298 (also S5L8922) is a 45 nm die shrunk version of the iPhone 3GS SoC and was introduced on September 9, 2009, at the launch of the third-generation iPod Touch.Ī series Evolution of Apple "A" series
It was manufactured by Samsung on a 65 nm process. It includes a 600 MHz single-core Cortex-A8 CPU and a PowerVR SGX535 GPU. The APL0298 (also S5L8920) is a PoP SoC introduced on June 8, 2009, at the launch of the iPhone 3GS. It was manufactured by Samsung on a 65 nm process. It includes a 533 MHz single-core ARM11 CPU and a PowerVR MBX Lite GPU. The APL0278 (also S5L8720) is a PoP SoC introduced on September 9, 2008, at the launch of the second-generation iPod Touch. The iPhone 3G and the first-generation iPod Touch also use it. It was manufactured by Samsung on a 90 nm process. It includes a 412 MHz single-core ARM11 CPU and a PowerVR MBX Lite GPU. The APL0098 (also 8900B 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.
They combine in one package a single ARM-based processing core ( CPU), a graphics processing unit ( GPU), and other electronics necessary for mobile computing. Apple first used SoCs in early versions of the iPhone and iPod Touch.
