Neoverse Compute Subsystems V3 (CSS V3)

Overview

The High-Performance Arm V3 Platform Performance-Optimized and Validated by Arm

Arm Neoverse CSS V3 is the fastest path to building high-performance, TCO-optimized cloud CPUs or custom AI accelerators on Arm. It delivers a high-performance, highly customizable Neoverse V3 subsystem, helping to reduce the time, cost, and risks of building high-performance custom silicon, and letting designers focus on product differentiation.

Key Features

  • The Fastest Path to Arm Confidential Computing VMs in the Cloud
    • Leveraging CSS V3 is the fastest way to deliver Neoverse V3 to market and supports the Arm Confidential Computing Architecture.
  • An Ideal Platform for Building AI Accelerators
    • CSS V3 combines technical capabilities, such as large, fast memory, a high-performance CPU, and high-speed die-to-die links, with the time-to-market advantage of the CSS engagement model.
  • A Pathway to Arm Chiplets
    • Neoverse CSS V3 is the first product built in conformance with the Arm Chiplet Architecture (CSA) specification. With CSS V3, partners can kick start an interoperable Arm chiplet ecosystem.
