On Tuesday, AMD announced three new additions to its desktop Ryzen CPU line: Ryzen 9 3900XT, Ryzen 7 3800XT, and Ryzen 5 3600XT. The new processor designs are expected to become generally available on July 7, the anniversary of the original launch date of 7nm Zen 2.

The new CPU designs take advantage of newly optimized 7nm process technology to offer higher performance at the same TDPs as Ryzen 3000 designs. The new 3000XT CPUs are drop-in replacements on AM4 motherboards that supported Ryzen 3000 CPUs and offer small (up to 4 percent) single-threaded performance improvements over their Ryzen 3000 counterparts.

Model	Cores/Threads	Boost/Base Frequency	Total Cache	TDP	Suggested retail price
Ryzen 9 3900XT	12/24	Up to 4.7GHz/3.8GHz	70MiB	105W	$499
Ryzen 7 3800XT	8/16	Up to 4.7GHz/3.9GHz	36MiB	105W	$399
Ryzen 5 3600XT	6/12	Up to 4.5GHz/3.8GHz	35MiB	95W	$249

Although the single-threaded performance improvements are small, the margins between CPUs in that stat tend to be razor-thin, and AMD says they're enough to take the coveted single-thread performance crown away from Intel. A 4 percent improvement to the Ryzen 9 3900X score shown on the CGDirector leaderboard would come out to 531—a few points higher than CGDirector's posted score for the i9-10900K, although a few points lower than our own Cinebench R20 result for that processor, using an NZXT Kraken fluid-cooler and Primochill Praxis open-air bench.
