Microsoft could make Maia 300 its primary inference engine with 2.5x memory bandwidth
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.
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.
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.
