Design
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.[1][6][5] The Monsoon cores are a 7-wide decode out-of-order superscalar design, while the Mistral cores are a 3-wide decode out-of-order superscalar design. The Mistral cores are based on Apple's Swift cores from the Apple A6.[9][failed verification] The A11 uses a new second-generation performance controller, which permits the A11 to use all six cores simultaneously,[10] unlike its predecessor the A10.
The A11 also integrates an Apple-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.[11] The A11 includes a new image processor which supports computational photography functions such as lighting estimation, wide color capture, and advanced pixel processing.[6]
The A11 is manufactured by
The A11 has video codec encoding support for HEVC and H.264. It has decoding support for HEVC, H.264, MPEG‑4 Part 2, and Motion JPEG.[15]

Neural Engine
The A11 also includes
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 nature made it difficult to attract AI research scientists.[17] Apple has since recruited people and multiple companies working on AI, and has published papers related to AI research.[17] In October 2016, Apple hired Russ Salakhutdinov as its director of AI research.[18]
