Microsoft plans multi-gigawatt Azure Maia deployments starting 2027
Microsoft says Maia 300 will begin production deployment in 2027 as part of Azure Maia expansion to multi-gigawatt scale, including 96-accelerator racks.
What you need to know
Microsoft announced on 12 October 2026 that it plans to expand its Azure Maia accelerator family to multi-gigawatt deployments starting in 2027, with Maia 300 beginning production deployment that year. The company also detailed a 96-accelerator rack design and performance claims versus current systems.
- Maia 200 already serves production workloads including Microsoft Copilot, with GitHub Copilot and Microsoft Foundry scheduled by year-end.
- Microsoft claims 40% more tokens per megawatt than leading GPU-based systems and up to seven times Maia 200's rack-scale token throughput.
- The 96-accelerator rack uses eight HBM4 stacks per chip, 18 TB/s memory bandwidth, 950-watt thermal-design power, and TSMC N2P compute chiplets.
Deployment timeline and scope
Microsoft said on 12 October 2026 that it intends to scale its Azure Maia accelerator family to deployments measured in multiple gigawatts beginning in 2027. The company plans for Maia 300 to enter production deployment that year.
Maia 200 is already running production workloads, including Microsoft Copilot. GitHub Copilot and Microsoft Foundry are scheduled to follow by the end of the year, according to the announcement.
System specifications and performance claims
A 96-accelerator rack configuration is described with eight HBM4 stacks per chip, 18 TB/s peak memory bandwidth and 950 watts of chip thermal-design power. The rack combines 96 accelerators within 167 kW, and compute chiplets use TSMC N2P.
Microsoft expects 40% more tokens per megawatt than leading GPU-based systems and claims up to seven times Maia 200's rack-scale token throughput. These comparisons are the company's claims rather than independent tests. The planned 2027 systems are not currently deployed.
The announcement focuses on inference and on reducing data movement across compute, memory and networking.
