## Summary

Microsoft announced that its upcoming Maia 300 accelerator will become the main inference engine for Azure, targeting multi‑gigawatt deployments beginning in 2027. The chip swaps a modest 36% compute gain for 2.5x the memory bandwidth of the earlier Maia 200, focusing on memory‑bound decode workloads.

The design moves from a single‑die Maia 200 to a multi‑chiplet package built on TSMC’s N2P process, with separate dies for memory‑controller and I/O. Executives Scott Guthrie, Rani Borkar and Saurabh Dighe outlined the plan in a Microsoft blog post, noting the shift mirrors Google and Amazon’s move to in‑house silicon.

## Key points

- Maia 300 trades a modest 36% compute gain for 2.5x memory bandwidth versus Maia 200.
- Microsoft plans multi‑gigawatt Azure Maia deployments starting in 2027, making Maia the primary inference system.

## Why it matters

If Microsoft shifts to its own Maia chips, it reduces reliance on Nvidia, could reshape AI hardware pricing and influence the broader chip ecosystem.
