A15

A15 is an alphanumeric designation used across different domains, most notably as a model name for Apple's A15 Bionic system-on-a-chip, but also as a road designation in several countries and for other products.

Apple A15 Bionic: A mobile system-on-a-chip designed by Apple, introduced in 2021, built on a 5-nanometer process. It features a six-core CPU with two performance cores and four efficiency cores, and a five-core GPU in the iPhone 13 Pro and iPhone 13 Pro Max (four-core GPU in the iPhone 13 and iPhone 13 mini). It includes a 16-core Neural Engine and an updated image signal processor. The A15 provides improved performance and energy efficiency over its predecessor, the A14, and has been used in the iPhone 13 lineup as well as certain iPad models.

A15 in transportation: In national road networks, A15 denotes a primary or major route in several countries. In the United Kingdom, the A15 is a trunk road in the east of England. In France and other countries, similarly named A15 roads exist as major routes; the exact path and connections vary by country. These roads typically connect regional centers and can serve both local and through traffic.

Other uses: The A15 designation is also used in product lines, model numbers, and catalog identifiers across different industries, including electronics, automotive parts, and consumer goods. Because A15 is not tied to a single standard, context is needed to determine which A15 is being referenced.
