AMD Unveils EPYC 'Milan' 7003 CPUs, Zen 3 Comes to 64-Core Server Chips [tomshardware.com]

AMD unveiled its EPYC 7003 'Milan' processors today, claiming that the chips, which bring the company's powerful Zen 3 architecture to the server market for the first time, take the lead as the world's fastest server processor with its flagship 64-core 128-thread EPYC 7763. Like the rest of the Milan lineup, this chip comes fabbed on the 7nm process and is drop-in compatible with existing servers. AMD claims it brings up to twice the performance of Intel's competing Xeon Cascade Lake Refresh [tomshardware.com] chips in HPC, Cloud, and enterprise workloads, all while offering a vastly better price-to-performance ratio.

Milan's agility lies in the Zen 3 architecture and its chiplet-based design. This microarchitecture brings many of the same benefits that we've seen with AMD's Ryzen 5000 series chips that dominate the desktop PC market, like a 19% increase in IPC and a larger unified L3 cache. Those attributes, among others, help improve AMD's standing against Intel's venerable Xeon lineup in key areas, like single-threaded work, and offer a more refined performance profile across a broader spate of applications.

One interesting new SKU is the EPYC 7663, a 56-core, 112-thread CPU with 7 working cores on each of the 8-core chiplets.

Next up, Zen 4 "Genoa" [notebookcheck.net].
