Introduced during a keynote event on September 12 2017, the ''A11 Bionic'' features six {{arch|64}} [[CPU]] [[physical core|cores]]. Fabricated on [[TSMC]]'s [[10 nm process]], the A11 consists of two high-performance [[big cores]] which are said to be 25% faster than the {{\\|A10}} and four high-efficiency [[little cores]] said to be 70% faster than {{\\|A10}}. In the {{\\|A10}} Apple had two pairs of cores - two little and two big, with little cores operating at half the frequency of their big cores counterparts. A11 doubles the number of little cores. It's worth pointing out that in the A10 at any given time only a single pair was active. In the A11, with the introduction of Apple's 2nd generation "performance controller", this restriction has been removed. The system can now use all six cores at once and is said to offer up to 70% performance improvement in [[multi-threaded workloads]]. | Introduced during a keynote event on September 12 2017, the ''A11 Bionic'' features six {{arch|64}} [[CPU]] [[physical core|cores]].

The GPU is a three-core design which is said to deliver 30% higher performance while using half the power as the {{\\|A10}}. As with the previous microprocessor, the A11 incorporates a video encoder designed by Apple. Among other things, the encoder introduces two major features: faster video frame rates and real-time image analysis. |
− | Apple stated that the encoder is now capable of real-time image and motion analysis. This is done by dividing the screen into individual tiles (on the iPhone 8 this works out to 2 million tiles) which are analyzed each second for things such as textures and edges to predict whether the tile is displaying things such as grass, water, sky or movement. Based on those properties the encoder can optimize the video encoding algorithms for quality and compression level. | + | Apple stated that the encoder is now capable of real-time image and motion analysis.
