Cortex-A520 (Hayes) is a planned ultra-high efficiency Cortex microarchitecture being designed by ARM Holdings as a successor to the Cortex-A510 (Klein). Cortex-A520 is scheduled for introduction around the 2023 timeframe.

Process Technology[edit]

The Cortex-A520 was primarily designed to take advantage of TSMC's 4 nm (TSMC N4P).

Architecture[edit]

Key changes from Cortex-A510[edit]

  • Update to ARMv9.2-A [1]
  • Support only 64-bit applications
  • Up to 512 KiB of private L2 cache (from 256 KiB)
  • 8% peak performance improvement over the Cortex-A510 [2]
  • Add QARMA3 Pointer Authentication (PAC) algorithm support
