Microsoft has officially released its second-generation self-designed AI chip, the Maia 200. As an upgrade to the Maia 100 launched in 2023, Microsoft stated the Maia 200 features technological advancements enabling it to run high-performance AI models faster and with greater energy efficiency. The chip pack over 100 billion transistors, achieving computing power exceeding 10 petaflops at 4-bit precision and approximately 5 petaflops at 8-bit precision, marking a significant improvement over its predecessor. Microsoft claims the high-bandwidth memory on a single Maia 200 chip exceeds that of Amazon Web Services’ third-generation Trainium AI chip and Google's seventh-generation Tensor Processing Unit. Microsoft will deploy the Maia 200 chip to support OpenAI’s GPT-5.2 model and provide computational power for Microsoft Foundry and Microsoft 365 Copilot.
