The era of prompt-and-response AI is behind us. We are now firmly in the age of agentic AI and the world needs a new class of compute built for this reality. That is why the launch of the Arm® AGI CPU is a pivotal moment. And to harness that raw, bare-metal efficiency at scale, it requires an optimized, resilient, and securely designed operating system.

In the lead-up to Ubuntu Summit 26.04, Canonical and Arm are collaborating to certify the new Arm AGI CPU on Ubuntu 26.04 LTS (Resolute Raccoon).

A shared history: pioneering Arm infrastructure

Canonical didn’t just jump on the Arm bandwagon; we have been pioneering emerging architectures for decades. Our vision, as stated in the historic 2012 Ubuntu Server 12.04 LTS press release, was a “future in which low-energy, hyperscale servers come to dominate for many workloads.” Ubuntu 12.04 LTS was the first enterprise Linux distribution to provide support for Arm-based servers, laying the early groundwork for the hyperscale era. From those early 32-bit development boards, Canonical has treated Arm as a first-class citizen, evolving Ubuntu into the dominant OS for the 64-bit server market.

As hyperscalers transitioned to cloud-native Arm processors in 2018, Ubuntu became the go-to foundation, providing day 0 support for all public cloud Arm instances. Canonical’s commitment goes beyond the operating system itself. Our infrastructure suite – including MAAS, Openstack, MicroCloud, Ceph, LXD, and Canonical Kubernetes – has featured highly optimized, native Arm64 support for years. This has enabled seamless bare-metal provisioning and orchestration, ensuring that when new Arm64 silicon drops, the software ecosystem is already waiting.

The new benchmark: Arm AGI CPU

For 35 years, Arm has licensed its IP to power the world’s computing. The introduction of the Arm AGI CPU expands this platform strategy, giving the ecosystem the ultimate flexibility to build on Arm – whether licensing IP, adopting Arm Neoverse® CSS, or deploying Arm-designed silicon. Arm AGI CPU is a high-performance engine built specifically to address the power and density constraints of modern AI workloads.

Hardware highlights include:

• Massive compute density: Up to 136 Arm Neoverse V3 cores spread across a dual-chiplet design.
• Efficiency: Manufactured on TSMC’s 3nm process, delivering maximum throughput at 300W TDP.
• Sub-100ns Memory Latency: 12 channels of DDR5 memory support, delivering 6GB/s of memory bandwidth per core to eliminate data starvation in real-time AI inference.
• Rack-scale economics: The 1OU dual-node reference design packs 272 dedicated cores per server unit, completely reshaping data center economics.

“The shift to agentic AI demands a new class of infrastructure where performance, efficiency, and scalability are engineered together from the ground up. By collaborating with Canonical to certify Ubuntu 26.04 LTS on Arm AGI CPU, we are enabling developers and enterprises to deploy next-generation AI workloads with the performance density, power efficiency, and software readiness required for the agentic era.”— Eddie Ramirez, VP of Go-to-Market, Cloud AI Business Unit, Arm

Ubuntu 26.04 LTS on Arm AGI CPU: hyper-efficient AI infrastructure

In high-stakes data centers, silicon is only as powerful as the software running on it. To extract every ounce of performance from the Arm AGI CPU, Ubuntu 26.04 LTS – backed by Canonical’s full-stack infrastructure suite – provides a secure, resilient, and frictionless foundation.

• Cutting-edge kernel 7.0 with 15-year support: Ubuntu 26.04 LTS ships with the Linux 7.0 kernel, bringing the latest upstream kernel innovations directly to enterprise environments. Backed by up to 15 years of enterprise maintenance with Ubuntu Pro, this release natively unlocks advanced Arm64 features like MPAM and nested virtualization.
• Arm64 kernel livepatching: In the world of continuous agentic AI, downtime is unacceptable. For the first time, Canonical’s Kernel Livepatch is available for Arm64 servers, allowing operators to apply critical security updates to the kernel without ever rebooting.
• Memory safety at the core: Ubuntu 26.04 LTS integrates Rust into the system layer (such as sudo-rs and coreutils), aligning perfectly with hardware-enforced security capabilities, like MTE, built into the Neoverse V3 architecture.
• Out-of-the-box optimization: Ubuntu certification brings rigorous, continuous validation in Canonical labs for the entire infrastructure portfolio to deliver secure, stable, and highly performant day-one deployments on certified hardware.

“The long-standing collaboration between Canonical and Arm has consistently driven  the evolution of enterprise infrastructure. Our joint efforts to certify the Arm AGI CPU on Ubuntu 26.04 LTS ensures a secure, dependable foundation to orchestrate agentic AI in data centers and cloud”— Cindy Goldberg, VP of Cloud and Silicon Partnerships at Canonical
