ARM Cortex-A720

The ARM Cortex-A720 is a CPU core model from Arm unveiled in TCS23, it serves as a successor of the CPU core ARM Cortex-A715, Cortex-A700 CPU cores series generally focus on high performance and efficiency, the CPU core can be paired with other cores in its family like ARM Cortex-X4 or/and ARM Cortex-A520 in a CPU cluster. It can be used as either "big" or "LITTLE".[1][2][3][4][5][6]
