The ARM Cortex-A715 is the second generation ARMv9 "big" Cortex CPU. Compared to its predecessor the Cortex-A710 the Cortex-A715 CPU is noted for having a 20% increase in power efficiency, and 5% improvement in performance. The Cortex-A715 shows comparable performance to the previous generation Cortex-X1 CPU.
This generation of chips starting with the A715 drops native 32-bit support. It forms part of Arm's Total Compute Solutions 2022 (TCS22) along with Arm's Cortex-X3, Cortex-A510, Arm Immortalis-G715 and CoreLink CI-700/NI-700.
Architecture changes in comparison with ARM Cortex-A710 The processor implements the following changes:
Decode width: 5 (increased from 4) Removed micro-op (MOP) cache (previously 1.5k entries)
