Arm Unveils First In-House 'AGI CPU' in 35-Year History — Meta First Customer, OpenAI and Cerebras Also On Board

Semiconductor design giant Arm Holdings has announced the 'AGI CPU,' its first in-house, production-ready chip in the company's 35-year history, as reported by TechCrunch. This marks a landmark strategic shift from its long-standing business model of exclusively licensing semiconductor designs to other companies.

The AGI CPU — where 'AGI' stands for 'Agentic AI Infrastructure' — is a data center processor specifically designed for the orchestration and management tasks required to run large-scale AI systems efficiently. Co-developed with Meta, the chip features up to 136 Arm Neoverse V3 cores, is built on TSMC's 3nm process, and operates within a 300-watt TDP. It supports 12 channels of high-speed DDR5 memory and 96 PCIe Gen6 lanes.

Meta will be the first customer, deploying the AGI CPU alongside its own custom MTIA accelerators. Arm has also secured commitments from other major tech players, including OpenAI, Cerebras, and Cloudflare, who will use the CPU to enhance their AI infrastructure. Arm claims the new chip can deliver more than double the performance per rack compared to current x86 systems for specific AI workloads.

This move presents a direct challenge to Intel and AMD's dominance in the x86 server market while also putting Arm in competition with its own partners like NVIDIA, which produces the Arm-based Grace CPU, and cloud providers such as AWS and Google who design their own Arm-based server chips. Arm has emphasized that this new venture will operate in parallel with its existing IP licensing and Compute Subsystems (CSS) businesses, with a committed multi-generational roadmap.

Arm is also offering reference server platforms developed with Supermicro, including a standard 10U air-cooled design and a high-density 200kW liquid-cooled configuration capable of housing over 45,000 cores in a single rack. Against the backdrop of explosive data center demand in the AI era, this represents a historic step for Arm as it moves up the value chain from chip designer to silicon provider.
