Apple A10

The Apple A10 Fusion is a 64-bit (SoC), designed by Apple Inc. and manufactured by TSMC. It first appeared in the iPhone 7 and 7 Plus, which were introduced on September 7, 2016. It is also used in the 6th and 7th-generation iPad, and 7th-generation iPod touch. The A10 is the first Apple-designed quad-core SoC, with two high-performance cores and two energy-efficient cores. Apple states that it has 40% greater CPU performance and 50% greater graphics performance compared to its predecessor, the Apple A9.
==Design==
The A10 (internally, T8010) is built on TSMC's 16 nm process and contains 3.28 billion transistors (including the GPU and caches) on a die size of 125 mm2. It features two Apple-designed 64-bit 2.34 GHz cores called Hurricane, each with a die size of 4.18 mm2. As the first Apple-produced quad-core SoC, it has two high-performance cores designed for demanding tasks like gaming, while also featuring two energy-efficient Apple-designed 64-bit 1.05 GHz cores codenamed Zephyr at 0.78 mm2 for normal tasks in a configuration similar to the technology.
Unlike most implementations of big.LITTLE, such as the Snapdragon 820 or Exynos 8890, only one core type can be active at a time, either the high-performance or low-power cores, but not both. Thus, the A10 Fusion appears to software and benchmarks as a dual core chip. Apple claims that the high-performance cores are 40% faster than Apple's previous A9 processor and that the two high-efficiency cores consume 20% of the power of the high performance Hurricane cores; they are used when performing simple tasks, such as checking email. A new performance controller decides in realtime which pair of cores should run for a given task in order to optimize for performance or battery life. The A10 has an of 64  for data and 64 KB for instructions, an of 3  shared by both cores, and a 4 MB L3 cache that services the entire SoC.
The new 6-core @ 900 MHz GPU built into the A10 chip is 50% faster while consuming 66% of the power of its A9 predecessor. Further analysis has suggested that Apple has kept the GT7600 used in Apple A9, but replaced portions of the based GPU with its own proprietary designs. These changes appear to be using lower floating-point numbers, allowing for higher-performance and lower power consumption.
Embedded in the A10 is the M10 motion coprocessor. The A10 also includes a new which Apple says has twice the throughput of the prior image processor. The A10 adds hardware encoding for and HEVC.Apple has chosen HEVC as its next-generation video codec. 8 June 2017.
The A10 is packaged in a new InFO packaging from TSMC which reduces the height of the package. In the same package there are also four RAM chips integrating 2 GB of RAM in the iPhone 7, the 6th-generation iPad, and the 7th-generation iPod touch, or 3 GB in the iPhone 7 Plus and the 7th-generation iPad.
