The ARM Cortex-A710 is the successor to the ARM Cortex-A78, being the First-Generation Armv9 "big" Cortex CPU. It is the companion to the ARM Cortex-A510 "LITTLE" efficiency core. It was designed by ARM Ltd.'s Austin centre.{{Cite web |title=Arm Announces Mobile Armv9 CPU Microarchitectures: Cortex-X2, Cortex-A710 & Cortex-A510 |url=https://www.anandtech.com/show/16693/arm-announces-mobile-armv9-cpu-microarchitectures-cortexx2-cortexa710-cortexa510 |access-date=2021-08-13 |website=www.anandtech.com}} It is the fourth and last iteration of Arm's Austin core family.
It forms part of Arm's Total Compute Solutions 2021 (TCS21) along with Arm's Cortex-X2, Cortex-A510, Mali-G710 and CoreLink CI-700/NI-700.{{Cite web |date=2021-05-25 |title=Arm Total Compute solutions powering decade of compute - Architectures and Processors blog - Arm Community blogs - Arm Community |url=https://community.arm.com/arm-community-blogs/b/architectures-and-processors-blog/posts/total-compute-solutions |access-date=2023-09-16 |website=community.arm.com |language=en}}
Architecture changes in comparison with ARM Cortex-A78
The processor implements the following changes:
- Rename / Dispatch width: 5 (decreased from 6).
- 10-cycle pipeline (decreased from 11).
- One of only two ARMv9 cores to support EL0 AArch32, along with the ARM Cortex-A510.
Improvements:
- 30% more power efficient than Cortex-A78.
- 10% uplift in performance compared to Cortex-A78{{Cite web |last=Ltd |first=Arm |title=Cortex-A710 |url=https://www.arm.com/products/silicon-ip-cpu/cortex-a/cortex-a710 |access-date=2021-08-12 |website=Arm {{!}} The Architecture for the Digital World |language=en}}
