Microsoft Maia 300
Maia 300 is Microsoft's next inference accelerator, with compute chiplets on TSMC N2P and eight HBM4 stacks delivering 18 TB/s at 950 W. Microsoft puts 96 in each rack and starts production deployments in 2027. Sources and verification dates.
Every published figure
Source per value- Owner The company that specified the chip and runs it in its own cloud, data centers or products.
- Microsoft 1
- Role What the owner says the chip is for: training, inference, both, or a general-purpose server CPU.
- Inference 1
- Foundry The fab that manufactures the die (TSMC, Samsung, SMIC, Intel).
- TSMC 1
- Node Process node as the owner or foundry states it, for example 'TSMC N3' or '7 nm'.
- TSMC N2P 1
- Memory On-package memory type (HBM2e, HBM3, HBM3E, LPDDR5) or, for CPUs, the memory the socket drives (DDR5).
- HBM4 1
- Memory bandwidth TB/s Peak memory bandwidth per chip in TB/s, as published.
- 18 1
- Precision note What the throughput figures mean: dense or sparse, which precision, per chip or per package, and any figure the owner states only in another unit.
- Microsoft gives no per-chip FLOPS; enhanced MXFP4 support. A 96-accelerator rack holds 27.6 TB of HBM (per-chip capacity not stated) and delivers up to 7x Maia 200 rack throughput. pod_chips is the rack size; scale-up domain not stated separately. 1
- Power W Chip or package power in watts as published (TDP, TBP or typical power; the source says which).
- 950 1
- Largest pod chips The largest scale-up domain the owner states: chips per pod, UltraServer, supernode or rack joined by the chip-to-chip interconnect.
- 96 1
- Status Announced: public roadmap without verified deployment. Sampling: first silicon or limited internal use. Preview: customers can request early access, without a GA claim. Deployed: stated production use or general availability. Discontinued: program stopped.
- Announced 1
- Announced Year the owner first announced the chip publicly.
- 2,026 1
- Deployment scale The largest deployment the owner or a named report states: chip counts, clusters, gigawatts or regions.
- Production deployments begin in 2027 as part of a multi-gigawatt Azure Maia rollout (Microsoft) 1
