Architecture changes in comparison with ARM Cortex-X1
The processor implements the following changes:
* 10 cycle pipeline down from 11, created by reducing the dispatch stage from 2 cycles to 1
* reorder buffer increased by 30% from 224 entries to 288
* dTLB increased by 20% from 40 entries to 48
* SVE2 SIMD support
*Bfloat16 data type support
* Support for Aarch32 removed
*Comparing the Cortex-X2 with 8MB of L3 cache to the Cortex-X1 with 4MB of L3 cache:
**16% greater integer performance
**100% greater ML performance
Usage
* MediaTek
Dimensity 9000/9000+
