Ryzen 3000 brings 7-nanometer chips to desktop PCs

AMD's third-generation Ryzen desktop processors are available today, led by the twelve-core Ryzen 9 3900X. The family uses the new Zen 2 architecture and 7-nanometer processor chiplets alongside a separate input-output die.

The accompanying X570 platform introduces PCI Express 4.0, offering additional bandwidth for graphics cards and fast storage. Existing AM4 motherboards may support the processors with firmware updates, although features and compatibility vary by board.

The launch turns manufacturing strategy into a product advantage. Small CPU chiplets let AMD assemble several models without building every component on the newest process, while higher instructions-per-clock performance targets weaknesses of earlier Ryzen generations. Buyers should still compare application and game results, power use and cooling. Yet more cores are moving into ordinary desktops, giving students and creators greater local capacity for compiling, rendering and media work without entering workstation pricing.
