Microsoft Unveils Third-Gen Maia 300 AI Chip, Plans 1M+ Deployment

KEY FACTS

  • Microsoft has released Maia 300, its third-generation in-house AI chip, for internal AI workloads.
  • Microsoft plans to deploy more than one million Maia 300 chips next year.
  • Maia 300 uses a chiplet architecture, with its core die built on TSMC's 2-nanometer process.
  • Each rack houses 96 chips and draws about 167 kilowatts of power.
  • Microsoft claims its useful compute per megawatt is about 40% higher than mainstream GPU systems.

PHYSIX OBSERVATION

By pushing its in-house chip to a third generation and committing to a million-unit deployment plan, Microsoft shows that cloud providers' determination to reduce dependence on Nvidia has moved from tentative trials to large-scale substitution. If the chiplet plus 2-nanometer route truly delivers the claimed 40% efficiency advantage, bargaining power will tilt toward buyers, but real-world workload performance still needs verification.
