A14

A14 is a designation used for several unrelated items in different domains, most notably a major road in the United Kingdom and a generation of Apple silicon. As a road designation, A14 refers to a primary trunk road in East Anglia that runs roughly east–west and serves as a corridor for freight and regional traffic, connecting coastal ports with inland markets and forming part of a broader cross-country route.

In the field of technology, A14 Bionic refers to Apple's system on a chip introduced in 2020. It was the first Apple-designed SoC manufactured on a 5-nanometer process by TSMC. The A14 Bionic comprises a six-core central processing unit with two high-performance cores and four efficiency cores, a four-core graphics processing unit, and a 16-core Neural Engine for machine learning tasks. It contains about 11.8 billion transistors and delivers improved performance and energy efficiency relative to its predecessors.

The A14 designation thus appears in very different contexts: a transport infrastructure component used to describe a major UK road, and a cutting-edge mobile processor that powers devices in Apple’s iPhone 12 family and the iPad Air (4th generation).
