Microsoft Unveils Maia 300 Chip and Plans for Massive Data Centers
Microsoft stated that the Maia 300 rack featuring 96 accelerators will deliver up to seven times the throughput of the Maia 200 and 40% higher performance per megawatt, with production deployment set for 2027.
Microsoft revealed details of its new Azure Maia 300 chip, stating that a single rack featuring 96 accelerators will deliver up to seven times the throughput of a Maia 200 rack, according to a report by The Register.
The company explained that the new system provides 40% higher processing power per megawatt than leading GPU-based systems.
It stated that each chip includes eight HBM4 high-bandwidth memory stacks offering up to 18 terabytes per second of bandwidth, significantly boosting data transfer speeds within the system.
Microsoft plans to begin production deployment in 2027, scaling toward a multi-gigawatt operational capacity as part of an expanding race among tech giants to build AI infrastructure.
What do these terms mean?
