Microsoft unveils Maia 300 and plans multi-gigawatt Maia deployments from 2027

Microsoft has announced Maia 300, the third generation of its Azure Maia AI accelerator, and says it will scale the Maia family to multi-gigawatt deployments starting in 2027, when Maia 300 production deployments also begin. Satya Nadella described it on X as Microsoft’s “biggest bet yet” on its own silicon.

The current chip, Maia 200, is in production and serves Microsoft Copilot; GitHub Copilot and Microsoft Foundry are due to follow by the end of 2026.

The chip

Microsoft designed Maia 300 first for inference, the work of running trained models: reasoning over long inputs, chat products that need fast responses and multi-step agent tasks. It expects the chip to deliver 40% more tokens per megawatt than leading GPU-based systems.

Key numbers

• Against a Maia 200 rack: up to 7 times the token throughput and up to 2.5 times more performance per watt
• Per chip: 2.5 times the memory bandwidth of Maia 200 and 33% more capacity
• Per rack: 167 kilowatts, double the accelerator density of Maia 200, with 27.6 TB of HBM and 1.7 PB/s of combined bandwidth

Microsoft plans to say more about its AI strategy at Microsoft Ignite 2026, from 17 to 20 November in San Francisco and online.
