Each figure in Microsoft’s own words

one chip, dense compute; memory is high-bandwidth memory

Memory: 64 GB provide a total of 1.8 terabytes per second of bandwidth and 64 gigabytes of capacity Inside Maia 100: Revolutionizing AI Workloads with Microsoft's Custom AI Accelerator
Memory bandwidth: 1.8 TB/s provide a total of 1.8 terabytes per second of bandwidth and 64 gigabytes of capacity Inside Maia 100: Revolutionizing AI Workloads with Microsoft's Custom AI Accelerator
Maximum power: 700 W Designed to support up to 700W TDP but provisioned at 500W Inside Maia 100: Revolutionizing AI Workloads with Microsoft's Custom AI Accelerator

Microsoft publishes no compute figures for Maia 100 on its own pages; the figures shown at Hot Chips 2024 are on hotchips.org, not a Microsoft site. Power is the 700 W design limit; Microsoft says the chip is provisioned at 500 W. No Microsoft page found says Maia 100 is in production or in service, so delivery is null.
