Several years ago, AMD adopted a multi-chiplet design for its client desktop and data center processors well ahead of its rivals. Back then, it was the only way for AMD to offer products with higher core counts than rival Intel, and now the move is seen as a strategic pivot towards an inevitable multichiplet design methodology. Today, Sam Naffziger, senior vice president and corporate fellow at AMD, thinks about how the Universal Chiplet Interconnect Express (UCIe) specification will create a chiplet ecosystem and enable custom multi-chiplet design.
For modular multichiplet designs, a high-performance, low-latency, and low-power interface is a must. The Infinity Fabric interface enabled AMD to build unique EPYC, Ryzen, and now Instinct MI300-series processors with unrivaled core counts, performance, and feature sets, Naffziger explained in a YouTube video conversation with Mark Papermaster, AMD's chief technology officer.
