Arm unveils AGI CPU

A central processing unit is the general-purpose chip that moves data, schedules tasks and keeps servers busy while graphics processors handle the heavy math. On March 24, Arm said it will sell its own data-center CPU for the first time, a new chip called the AGI CPU built for “agentic” artificial-intelligence systems. (newsroom.arm.com) Arm said Meta co-developed the chip and will deploy it in production infrastructure later in 2026. CNBC reported Meta is the first official customer and that Arm disclosed seven other committed customers, including OpenAI, Cloudflare and SAP. (newsroom.arm.com) (cnbc.com) The first implementation uses up to 136 Neoverse V3 cores, 128 megabytes of shared system-level cache, 12 channels of DDR5-8800 memory and PCI Express Gen6 input-output links. Arm’s product brief says the chip is built on the Armv9.2 instruction set, runs at up to 3.2 gigahertz all-core and 3.7 gigahertz boost, and includes dual 128-bit Scalable Vector Extension 2 units in each core. (arm.com) “Agentic” artificial intelligence refers to systems that break a job into many smaller steps, call tools, fetch data and coordinate multiple models over long sessions. Arm said those workloads shift pressure onto the CPU, memory and networking fabric because every graphics-processor cluster still needs a host processor to feed data, route requests and manage storage. (newsroom.arm.com) Arm said the AGI CPU can deliver more than 2 times the performance per rack of x86 platforms in this class of infrastructure. The company also said data centers may need more than 4 times today’s CPU capacity per gigawatt as artificial-intelligence systems scale. (newsroom.arm.com 1) (newsroom.arm.com 2) The launch changes Arm’s business model as much as its product line. For decades, Arm licensed processor designs and instruction-set technology to companies such as Apple, Amazon, Nvidia and Qualcomm; this is the first time in its 35-year history that it is offering production silicon directly. (newsroom.arm.com) (eetimes.com) Arm said the chip will be manufactured by Taiwan Semiconductor Manufacturing Co. on a 3-nanometer process and sold through original design manufacturers including Jabil, Inventec and Wistron. The company said customers can buy the AGI CPU as finished silicon or use the same platform through Arm Compute Subsystems and licensable intellectual property. (siliconangle.com) (newsroom.arm.com) The move also puts Arm closer to some of its own customers. Arm said the AGI CPU will work alongside Meta’s in-house Meta Training and Inference Accelerator, while Meta separately expanded its custom artificial-intelligence chip partnership with Broadcom on April 14. (newsroom.arm.com) (siliconangle.com) Arm is pitching the chip as a way to sell more of the stack as artificial-intelligence data centers get denser and more specialized. The opening bet is that the next bottleneck in AI infrastructure is not only the accelerator, but the CPU that keeps the whole rack moving. (newsroom.arm.com)
