The ARM Cortex-A720 is a CPU core model from Arm[1][2] unveiled in 2023.[3] It serves as a successor to the ARM Cortex-A715.[4]
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[5] in a CPU cluster. It can be used as either "big" or "LITTLE".[6]
Architecture changes in comparison with ARM Cortex-A715
[edit]- Update to ARMv9.2
- 15% peak performance improvement over the Cortex-A715
