The ARM Cortex-A720 is a CPU core model from Arm unveiled in 2023. It serves as a successor to the ARM Cortex-A715.

Cortex-A700 CPU cores series focus on balanced performance and efficiency, and the CPU core can be paired with other cores in its family such as the high performance ARM Cortex-X4 or/and high efficiency ARM Cortex-A520 in a CPU cluster. It can be used as either "big" or "LITTLE".

Architecture changes in comparison with ARM Cortex-A715

  • Update to ARMv9.2
