Apple A11 The Apple A11 Bionic is a 64-bit ARM-based system on a chip (SoC), designed by Apple Inc.[6] and manufactured by TSMC.[1] It first appeared in the iPhone 8, iPhone 8 Plus, and iPhone Apple A11 Bionic X which were introduced on September 12, 2017.[6] It has two high-performance cores which are 25% faster than the Apple A10 and four high-efficiency cores which are up to 70% faster than the energy-efficient cores in the A10.[6][7] Contents Design Neural Engine Products that include the Apple A11 Bionic See also References Produced From Design September 12, 2017 to [1][6][4] The A11 features an Apple-designed 64-bit ARMv8-A six-core CPU, with two high-performance cores at 2.39 GHz, called Monsoon, and four energy-efficient cores, called Mistral. present The A11 uses a new second-generation performance controller, which permits the A11 to use all six cores simultaneously,[8] unlike its predecessor the A10. The A11 also integrates an Apple- Designed by Apple Inc. designed three-core graphics processing unit (GPU) with 30% faster graphics performance than the A10.[6] Embedded in the A11 is the M11 motion coprocessor.[9] The A11 includes a new Common [1] image processor which supports computational photography functions such as lighting estimation, wide color capture, and advanced pixel processing.[6] TSMC manufacturer(s) [1] [7] 2 [10] The A11 is manufactured by TSMC using a 10 nm FinFET process and contains 4.3 billion transistors on a die 87.66 mm in size, 30% smaller than the A10. It is manufactured in a Max. CPU clock to 2.39 [3] [10] [11][12] package on package (PoP) together with 2 GB of LPDDR4X memory in the iPhone 8 and 3 GB of LPDDR4X memory in the iPhone 8 Plus and iPhone X. rate GHz[2] Min. feature size 10 nm[1] Neural Engine Instruction set A64 The A11 also includes dedicated neural network hardware that Apple calls a "Neural Engine". This neural network hardware can perform up to 600 billion operations per second and is used Microarchitecture ARMv8‑A for Face ID, Animoji and other machine learning tasks.[8] The neural engine allows Apple to implement neural network and machine learning in a more energy-efficient manner than using compatible [13][14] either the main CPU or the GPU. Bloomberg says that the neural engine is the fruit of Apple's efforts to improve its AI team, since the 2015 report by Bloomberg that Apple's secretive Product code APL1W72[3] nature made it difficult to attract AI research scientists.[14] Apple has since recruited people and multiple companies working on AI, and has published papers related to AI research.[14] In Cores Hexa-core October 2016, Apple hired Russ Salakhutdinov as its director of AI research.[15] (2× Monsoon + Products that include the Apple A11 Bionic 4× Mistral)[1][4] iPhone 8 and 8 Plus iPhone X L1 cache 32 KB instruction, 32 KB See also data[5] Apple mobile application processors, the range of ARM-based mobile processors designed by Apple for their consumer electronic devices L2 cache 8 MB L3 cache unknown[5] References Predecessor Apple A10 Fusion 1.
