Microsoft Unveils Maia 200 AI Chip

Microsoft unveiled its second-generation artificial intelligence chip, the Maia 200, on Monday, marking a significant step in the company's efforts to enhance AI processing capabilities and lessen dependence on external hardware suppliers. The chip, designed primarily for AI inference tasks, began operations this week at a data center in Des Moines, Iowa, with additional deployments planned for a facility in Phoenix, Arizona, in the coming weeks.

The Maia 200 succeeds the original Maia 100, introduced in 2023, and features more than 100 billion transistors, delivering over 10 petaflops of performance at 4-bit precision and approximately 5 petaflops at 8-bit precision. Microsoft claims it provides three times the compute performance of Amazon Web Services' most advanced Trainium processor on certain AI benchmarks and surpasses Alphabet's Google latest tensor processing unit on others. Built by Taiwan Semiconductor Manufacturing Co. using 3-nanometer technology, the chip incorporates high-bandwidth memory and a substantial amount of static random-access memory, or SRAM, to improve speed for handling requests from numerous users in applications like chatbots.
