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. 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.
