A family of AI chips from AMD. Introduced in 2023, the Instinct MI300X is a GPU chip with 192GB of HBM3 memory. Multiple MI300X chips are used in AMD's Infinity Architecture Platform for high-end servers. See
high bandwidth memory.
In contrast, the MI300A features both GPUs and CPUs for use in high performance computing (HPC) as well as AI. For example, MI300A chips power the El Capitan supercomputer, which is expected to provide two quintillion floating point operations per second (2 exaFLOPS).
A different approach than Intel and other chip designers, AMD uses chiplets, which enables them to mix and match processing functions more easily than designing one gigantic chip from scratch. See
MCM.
