SuccessorARM Cortex-A725

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
  • Can down to same size as Cortex-A78 with 10% performance improvement
  • Area optimize configuration for no area cost vs Cortex-A78
  • Down L2 cache hit latency to 9 cycles (from 10 cycles)
  • Down mispredict latency to 11 cycles (from 12 cycles)[6]
  • x2 L2 bandwidth
  • DSU-120
    • Up to 14 cores (up from 12 cores)
    • Up to 32 MiB of shared L3 cache (increased from 16 MiB)
