Features and Benefits

Performance Uplift of 50% and Vector Flexibility

Delivers an incredible 50 percent IPC performance uplift over the Neoverse N1 core thanks to a new micro-architecture designed for maximum per-core performance.

Scalable Vector Extension

Includes two 256b SVE vector units, doubling the integer and floating-point execution capability of Neoverse N1 per core for better HPC and AI/ML performance. SVE was invented in collaboration with Fujitsu for the Fugaku project and enables vector-width agnostic programming. SVE enables code execution of vectors ranging from 128b to 2048b wide on Neoverse V1 without requiring recompilation.

Built for Balanced Systems Performance

Enables the deployment of high-bandwidth DDR5 and HBM2e/3 memory systems to unlock the full performance of Neoverse V1 cores. Designers can augment core performance with custom or third-party accelerators connected over the flexible CMN-700 interconnect.
