The ARM Cortex-A725 is a CPU core model from Arm unveiled in 2024. ^[1] It serves as a successor to the ARM Cortex-A720. 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-X925 or/and high efficiency ARM Cortex-A520 in a CPU cluster. It can be used as either "big" or "LITTLE". ^{[2] [3]}
