A73

A73 is an alphanumeric designation used in several unrelated domains. It commonly appears in technology and transportation, among other contexts, and the exact meaning depends on the field and country.

In technology, the ARM Cortex-A73 is a 64-bit central processing unit core designed by ARM Holdings. Introduced in 2016, it is part of ARM’s Cortex-A family and is used in mobile system-on-chips to balance performance with energy efficiency. The A73 core has been implemented in various SoCs to improve instruction throughput and battery life in smartphones and other devices, often in conjunction with newer co‑developed cores.

In road networks, A-designated roads are typically major routes within a national or regional system. The A73 designation is used for one or more roads in different countries, reflecting the local naming conventions for primary or significant arterial routes. The specific route, length, and status of any A73 road can vary by country and over time as networks are updated or reclassified.

Other uses of A73 exist but are less standardized and highly context-dependent. The designation can appear as a product code, model number, or internal identifier in various organizations. Because such uses are not universal, the meaning of A73 should be confirmed within the relevant domain or jurisdiction when encountered.
