At AMD’s Epyc launch few weeks ago, Lisa Su, Mark Papermaster, and the rest of the AMD Epyc team hammered home that AMD designed its new Zen processor core for servers first. This server-first approach has implications for performance, performance per watt, and cost perspectives in both datacenter and consumer markets.
AMD designed Epyc as a modular architecture around its “Zeppelin” processor die with its eight “Zen” architecture cores. To allow multi-die scalability, AMD first reworked its HyperTransport socket-to-socket system I/O architecture for use on a chip, across a multi-chip module (MCM), and for inter-socket connectivity. AMD has named this …
