AUSTIN—Today, AMD unveiled the first generation of Epyc, its new range of server processors built around its Zen architecture. Processors will range from the Epyc 7251—an eight-core, 16-thread chip running at 2.1 to 2.9GHz in a 120W power envelope—up to the Epyc 7601: a 32-core, 64-thread monster running at 2.2 to 3.2GHz, with a 180W design power.
AMD initially revealed its server chips, codenamed "Naples," earlier this year. Since then, we've known the basics of the new chips: they'll have 128 PCIe lanes and eight DDR4 memory controllers and will support one or two socket configurations. With today's announcement, we now know much more about how the processors are put together and what features they'll offer.
