Arm Cortex-X3 + Cortex-A715 Announced As Second-Gen Armv9 CPUs

Arm today announced their second-generation Armv9 CPU designs with the Cortex-X3 and Cortex-A715. Arm also refreshed the Cortex-A510 to allow for more cores and a power reduction.

The Arm Cortex-X3 aims to deliver 25% improved performance compared to the latest Android flagship smartphone and up to 34% better performance against the latest mainstream laptop designs. That 34% figure Arm is using is based on single-threaded performance. For scaling up to laptop and desktop devices, the Cortex-X3 DSU can handle up to 12 cores and a 16MB L3 cache.
