The ARM Cortex-A710 is the successor to the ARM Cortex-A78, being the First-Generation Armv9 "big" Cortex CPU. ^[1] It is the companion to the ARM Cortex-A510 "LITTLE" efficiency core. It was designed by ARM Ltd.'s Austin centre. ^[2] It is the fourth and last iteration of Arm's Austin core family. ^[2]

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. ^[3]

Architecture changes in comparison with ARM Cortex-A78

The processor implements the following changes: ^[2]

• 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 ^[4]
• 2x ML uplift ^[1]
