Current obstacles

x86 ecosystem dominancex86 processors and their software ecosystems (Linux, virtualization, management tools) are entrenched in data centers; switching incurs migration costs.
Winning other hyperscalersMeta is the anchor customer, but scaling AGI CPU revenue requires winning commitments from Google, Amazon, Microsoft, and other major cloud providers.

Physics limits

Inference latency is set by memory access timeEven with low-latency memory, serving AI inference requires moving weights from storage to cache; memory bandwidth per core, not compute speed, is the bottleneck for large models.
Chip area and power density are linkedPacking 136 cores per chip generates heat; on-chip power density limits clock speed and core count, constrained by physics and process technology limits.

How it works

4 parts

Instruction set

Arm ARMv9 architecture

The AGI CPU implements Arm's ARMv9 instruction set, widely used in mobile and embedded systems but now extended for data center inference workloads.

Core design

Neoverse V3 cores

Each core is a high-performance, wide-issue out-of-order processor optimized for throughput and low latency, suitable for AI inference pipelines.

Memory subsystem

Low-latency memory hierarchy

Large L2 caches per core, coherent memory fabric, and fast DDR5 interfaces deliver high memory bandwidth for neural network weights and activations.

Scale to rack

Optical and electrical interconnects

Multiple AGI CPUs in a rack interconnect via Ethernet and optical links, enabling horizontal scaling for large AI inference clusters.

About Arm

The team behind Arm AGI CPU

Arm

Processor architecture, CPU design, AI accelerators

Arm designs processor architectures used in billions of devices. On March 24, 2026, Arm announced the AGI CPU, its first proprietary data center processor, targeting AI inference.

Over 350 billion Arm-based chips have shipped globally; 100% of the connected population uses Arm-based devices.
Arm's AGI CPU brings 2x the performance per rack versus x86 platforms for AI data centers, potentially saving $10B per gigawatt of capacity.
Meta, the first customer, is committing to multiple generations; Arm expects AGI CPU revenue of $15B annually by 2031.
