## Summary

[Arm Holdings](/en/entity/arm) has moved from pure IP licensor to direct silicon vendor. Its AGI CPU, unveiled
24 March 2026, the firm's first production chip in 35 years, packs up to 136 Neoverse V3 cores across
two dies on [TSMC's](/en/entity/tsmc) 3nm process, aimed at the ~$70B data-centre CPU market. CEO Rene Haas says
shipments begin by end-2026, with "material" financial impact from 2028. Alongside the chip, Arm released
the first public specification of its **Chiplet System Architecture (CSA)**, a standards play tackling
die-to-die physical-layer compatibility, with 60+ organisations engaged (complementing UCIe). The pivot
is double-edged: Arm now competes with the licensees, [Nvidia](/en/entity/nvidia), [Qualcomm](/en/entity/qualcomm),
hyperscalers, whose royalties fund it, while expanding its own addressable market.

## By the numbers

- 136, Neoverse V3 cores in the AGI CPU (two dies, TSMC 3nm).
- 35, years since Arm last shipped its own chip.
- ~$70B, data-centre CPU market Arm is now entering directly.
- 60+, organisations engaged with Arm's open Chiplet System Architecture (CSA).
- End-2026 / 2028, AGI CPU shipments start / "material" revenue impact.

## Why it matters

Arm's architecture sits under nearly every phone and an expanding share of servers; selling finished
silicon turns the toll-collector into a rival. If CSA becomes the chiplet stitching standard, Arm
controls both the cores and the interconnect, a quiet shift that could reshape who captures value in
disaggregated AI silicon. The risk is alienating the licensees who built its empire.

## What to watch

- First AGI CPU customers and any licensee pushback.
- CSA adoption vs UCIe as the chiplet interconnect standard.
- Whether hyperscalers buy Arm's chip or keep building their own custom Neoverse parts.

### deep enterprise-compute analysis
- **The Next Platform** (United States, en) — Reads the AGI CPU as Arm 'coming full circle', from licensing cores to selling finished AI-tuned server silicon. Stresses the conflict: Arm now competes with the licensees (Nvidia, Qualcomm, hyperscalers) that pay its royalties, a gamble that expands its addressable market while risking its IP relationships.
