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. 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.

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
• 2x ML uplift
