Announcing Arm AGI CPU: The silicon foundation for the agentic AI cloud era

Today, Arm is announcing the Arm AGI CPU, a new class of production-ready silicon built on the Arm Neoverse platform and designed to power the next generation of AI infrastructure.

For the first time in our more than 35-year history, Arm is delivering its own silicon products – extending the Arm Neoverse platform beyond IP and Arm Compute Subsystems (CSS) to give customers greater choice in how they deploy Arm compute – from building custom silicon to integrating platform-level solutions or deploying Arm-designed processors. It reflects both the rapid evolution of AI infrastructure and growing demand from the ecosystem for production-ready Arm platforms that can be deployed at pace and scale.

The rise of the agentic AI infrastructure

AI systems are increasingly operating continuously at global scale. Historically, the human was the bottleneck in computing – the pace at which people could interact with systems defined how quickly work could move through them. In the era of agentic AI, that constraint disappears as software agents coordinate tasks, interact with multiple models and make decisions in real time.

As AI systems run continuously and workloads grow in complexity, the CPU becomes the pacing element of modern infrastructure – responsible for keeping distributed AI systems operating efficiently at scale. In a modern-day AI data center, the CPU manages thousands of distributed tasks – orchestrating accelerators, managing memory and storage, scheduling workloads and moving data across systems – and now, with agentic AI, coordinating fan-out across large numbers of agents.

This shift places new demands on the CPU and that requires an evolution of the processor.

Arm Neoverse already underpins many of today’s leading hyperscale and AI platforms, including AWS Graviton, Google Axion, Microsoft Azure Cobalt and NVIDIA Vera. As AI infrastructure scales globally, partners across the ecosystem are asking Arm to do more. The Arm AGI CPU was created to address this shift.

Arm AGI CPU: Built for rack-scale agentic efficiency

Agentic AI workloads demand sustained performance at massive scale. The Arm AGI CPU is designed to deliver high per-task performance at sustained load across thousands of cores in parallel – all within the power and cooling limits of modern data centers.

Every element of the Arm AGI CPU – from operating frequency to memory and I/O architecture – has been designed to support massively parallel, high-performance agentic workloads in a densely populated rack deployment.

Arm’s reference server configuration is a 1OU, 2-node design – packing in two chips with dedicated memory and I/O for a total of 272 cores per blade. These blades are designed to fully populate a standard air-cooled 36kW rack – 30 blades delivering a total of 8160 cores. Arm has additionally partnered with Supermicro on a liquid-cooled 200kW design capable of housing 336 Arm AGI CPUs for over 45,000 cores.

In this configuration, the Arm AGI CPU is capable of delivering more than 2x the performance per rack compared to the latest x86 systems*, achieved through the fundamental advantages of the Arm architecture and careful matching of system resources to compute:

• Arm AGI CPU’s class-leading memory bandwidth means more effective threads of execution per rack; x86 CPUs degrade as cores contend under sustained load.
• High performance, efficient, single-threaded Arm Neoverse V3 CPU cores outperform legacy architectures; every Arm thread does more work.
• More usable threads and more work-per-thread compounds to massive performance gains per rack.

Early momentum across the AI ecosystem

The Arm AGI CPU is already seeing strong commercial momentum with partners at the forefront of scaling agentic AI infrastructure. Planned deployments span accelerator management, agentic orchestration and the densification of services, applications and tools needed for agentic task scale-out — as well as increased networking and data plane compute to support the AI data center.

Meta is our lead partner and customer, co-developing the Arm AGI CPU to optimize gigawatt-scale infrastructure for its Meta family of apps and to work alongside Meta’s own custom MTIA accelerators. Other launch partners include Cerebras, Cloudflare, F5, OpenAI, Positron, Rebellions, SAP, and SK Telecom – each working with Arm on the deployment of the Arm AGI CPU to accelerate AI-driven services across cloud, networking and enterprise environments. Commercial systems are now available for order from ASRockRack, Lenovo and Supermicro.

To accelerate adoption further, Arm is introducing the Arm AGI CPU 1OU Dual Node Reference Server, an Open Compute Project (OCP) DC-MHS standard form factor server. Arm plans to contribute this reference server design and supporting firmware, along with further contributions including system architecture specifications, debug frameworks and diagnostic and verification tooling applicable to all Arm-based systems. Further details will come at the upcoming OCP EMEA Summit.

A new chapter for Arm infrastructure

The launch of Arm AGI CPU represents a new chapter in Arm’s data center journey and continued leadership in computing innovation. As AI reshapes the industry, Arm remains committed to enabling progress across the ecosystem – meeting customers where they are, from hyperscale cloud providers to AI startups.

The Arm AGI CPU is the first offering of Arm’s new data center silicon product line and is available to order now. Follow-on products are committed, targeting best-in-class performance, scale and efficiency. This continues in parallel with the Arm Neoverse CSS product roadmap so that all Arm data center customers move forward together on platform architecture and software compatibility.

Entering this new chapter, our mission remains unchanged: to provide the compute foundation that enables innovation across industries. And the ecosystem is fully behind us: More than 50 leading companies across hyperscale, cloud, silicon, memory, networking, software, system design and manufacturing are supporting the expansion of the Arm compute platform into silicon. With Arm AGI CPU, we are not only defining the architecture of the AI-native data center, we are building it.
