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.

Features and Benefits

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.
