The ARM Cortex-X3 is the third generation X-series high-performance CPU core from Arm.[1][2][3] It forms part of Arm's Total Compute Solutions 2022 (TCS22) along with Arm's Cortex-A715, Cortex-A510, Immortalis-G715 and CoreLink CI-700/NI-700.[4]


Architecture changes in comparison with ARM Cortex-X2

The processor implements the following changes:[1][5][6]

  • Decode width: 6 (increased from 5)
  • Rename / Dispatch width: 8
  • micro-op (MOP) cache: 1.5k entries (reduced from 3k)
  • Reorder buffer (ROB): 320 entries (increased from 288)
  • Execution ports: 15
  • Pipeline length: 9 (reduced from 10)

Performance claims:

  • 25% peak performance improvement over the Cortex-X2 in smartphones (3.3GHz, 1MB L2, 8MB L3).[1][7]
  • 11% IPC uplift over the Cortex-X2, when based on the same process, clock speed, and cache setup (also known as ISO-process).[3]
  • 34% faster than an Intel Core i7-1260P (3.6GHz, 1MB L2, 16MB L3)[8]
