   Microsoft Maia 300 vs Nvidia Rubin: specs compared, no clear winner

   Microsoft unveiled Maia 300 on Oct. 12, 2026, and plans to expand its Azure Maia infrastructure to multi-gigawatt deployments starting in 2027, positioning the chip as its primary AI inference engine. Maia 300 pairs 288 GB of HBM4 and 18 TB/s peak bandwidth per accelerator at 950W, with 96 accelerators per rack totaling 27.6 TB of HBM4 and 167 kW; Nvidia's Rubin NVL72 lists 288 GB HBM4 and up to 22 TB/s per GPU, with 72 GPUs and 20.7 TB aggregate HBM4 per rack. Their efficiency claims use different baselines and no independent, workload-matched test exists: Microsoft says Maia 300 delivers 40% more tokens per megawatt than unnamed leading GPU systems, while Nvidia projects Rubin NVL72 at up to 10x the tokens per megawatt of GB200 NVL72, so neither can be declared faster.

   Microsoft unveils Maia 300, its third-gen in-house AI chip, for 2027 rollout

   Microsoft announced Maia 300 on October 12, its third-generation in-house AI accelerator, positioned as the “primary AI inference system” for Microsoft products and services and aimed at long-context reasoning, latency-sensitive conversation and sustained multi-step agentic tasks. Built on TSMC’s N2P process with a chiplet architecture that separates compute, memory-controller and I/O functions, it uses eight stacks of HBM4 with a claimed 18TB/s peak bandwidth inside a 950W thermal design power. Cloud chief Scott Guthrie says Maia 300 should deliver about 40 percent more tokens per megawatt than leading GPU-based systems, and up to 7x the rack-scale token throughput of Maia 200 in a 96-accelerator configuration; Microsoft plans multi-gigawatt Azure Maia deployments starting in 2027. Microsoft says it will not stop buying Nvidia or AMD GPUs entirely, and Maia 200 already runs production workloads such as Microsoft Copilot, GitHub Copilot and Microsoft Foundry. The performance figures come from Microsoft and have not been independently verified.
