This morning, AMD announced the next big thing for its Ryzen desktop CPU line—the Ryzen 4000 series, slated to arrive in Q3 2020.

Those of you who've been waiting breathlessly for Zen 3 architecture will need to keep waiting—Ryzen 4000 desktop CPUs are still built on 7nm, Zen 2 architecture. There also don't appear to be any performance recordbreakers in Ryzen 4000's desktop lineup: the highest-end SKU announced is the 65W 8 core / 16 thread Ryzen 7 Pro 4750G.
