AMD Instinct MI300X: A Generative AI Accelerator and Platform Architecture
Alan P. Smith, Vamsi Krishna Alla · IEEE Micro · 2025
AMD Instinct MI300X sets a new benchmark in generative artificial intelligence (AI) acceleration, combining architectural innovation with advanced system integration to tackle the ever-growing demands of modern AI workloads. Featuring a chiplet-based architecture, the MI300X employs the fourth-generation Infinity Fabric, eight-stack HBM3 memory, and CDNA 3 compute cores to deliver unparalleled performance for both inference and training tasks. Additionally, the MI300X is central to the AMD Infinity platform, which offers industry-standard scalability through universal baseboard designs, high-bandwidth interconnectivity, and robust system management features. This article provides a detailed exploration of the MI300X architecture, its Infinity platform integration, and its impact on generative AI applications.
