Abstract: The AMD Instinct MI300 Series, encompassing the MI300X and MI300A models, represents a pioneering integration of high-performance computing (HPC) and artificial intelligence (AI) capabilities within a single package, leveraging advanced silicon and packaging technologies. Designed for both CPU-hosted PCIe devices (MI300X) and self-hosted accelerated processing units (APUs) (MI300A), these accelerators utilize AMD's chiplet architecture and advanced packaging to combine data center class CPU, GPU compute, AMD Infinity Cache, and an 8-stack HBM3 memory system, aiming to deliver over 5TBps of peak bandwidth. The MI300X targets large model AI training and inference in traditional server setups, while the MI300A is optimized for high-density HPC systems, facilitating seamless pointer sharing between CPU and GPU kernels. This new series not only extends the hybrid bonding technology for enhanced performance and efficiency but also introduces spatial partitioning and advanced memory side caching techniques, significantly advancing AMD's capabilities in the AI and HPC domains.
