<P> The Apple A11 Bionic is a 64 - bit ARM - based system on a chip (SoC), designed by Apple Inc. and manufactured by TSMC . It first appeared in the iPhone 8, iPhone 8 Plus, and iPhone X which were introduced on September 12, 2017 . 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 . </P> <P> The A11 features an Apple - designed 64 - bit ARMv8 - A six - core CPU, with two high - performance cores, called Monsoon, and four energy - efficient cores, called Mistral . The A11 uses a new second - generation performance controller, which permits the A11 to use all six cores simultaneously, 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 . Embedded in the A11 is the M11 motion coprocessor . The A11 includes a new image processor which supports computational photography functions such as lighting estimation, wide color capture, and advanced pixel processing . The A11 also includes dedicated neural network hardware that Apple calls a "Neural Engine", which can perform up to 600 billion operations per second, used for Face ID, Animoji and other machine learning tasks . </P> <P> 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, 41% smaller than the A10 . It is manufactured in a 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 . </P> <Ul> <Li> iPhone 8 and 8 Plus </Li> <Li> iPhone X </Li> </Ul>
