Cortex-A73

The Cortex-A73 processor is the most-efficient high-performance processor that implements the Armv8-A architecture.

Information on Cortex-A73.

Getting Started

The Cortex-A73 processor can be paired with the Cortex-A53 or Cortex-A35 processor in a big.LITTLE configuration for mobile applications. The Cortex-A73 processor cluster has one to four cores, each with their L1 instruction and data caches, together with a single shared L2 unified cache.
