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]
Usage
- MediaTek Dimensity 9200[8]
- Qualcomm Snapdragon 8 Gen 2[9]
