Microsoft unveils Maia 300 AI chip, plans to scale deployments

Microsoft just unveiled its Maia 300 AI chip, the third version of its in-house silicon, and said it will shift most of its AI services to these custom chips starting in 2027. The new chips are expected to run everything from Microsoft Copilot to GitHub Copilot, replacing much of Microsoft’s reliance on NVIDIA GPUs. Microsoft says Maia 300 will process 40% more AI workload per unit of power than leading GPUs, with large-scale rollout planned for its own products and services.

• Large-scale deployment to start in 2027
• Will replace NVIDIA GPUs for most internal AI workloads
• Claims 40% higher efficiency than top GPU systems
