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[edit]

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]

One thought on “Cannabaceae”

  1. Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
