AMD's Epyc 7000-series CPUs revealed
 

AMD has been in a data-center desert for many years. Abu Dhabi Opterons marked the company's last serious foray into the market in 2012, and since then, Intel's market share of all server chips has been at least as high as 99.2%. Long-running murmurs of ARM chips disrupting Intel's lock on the data center haven't translated into major threats to Xeons yet. AMD's own effort to produce ARM cores that were socket-compatible with its x86 CPUs, called Project Skybridge, never produced a shipping product, and the company abandoned it in 2015. The last update to AMD's data center roadmap promised the high-performance K12 ARM core for this year, too, but we haven't heard a peep of it since. Despite those various pretenders to the throne, x86 remains the dominant instruction set in the data center, and Xeons are its avatar.
