These new CPU models—the Ryzen 9 3900XT, Ryzen 7 3800XT, and Ryzen 5 3600XT—are minor refreshes of the existing Ryzen 9 3900X, Ryzen 7 3800X, and Ryzen 5 3600X models and add a couple hundred MHz extra boost clock speed to the original versions.

That's generally going to be the Ryzen 9 3950X, which didn't get an XT upgrade and outperforms the Ryzen 9 3900XT in most respects.

We don't expect you to take our word for it on the performance difference of Ryzen 3000 X-series versus Ryzen 3000 XT-series—above, you'll find the numbers that make that case.

The first two charts compare the older X series processors to their closest XT series equivalent—so, Ryzen 9 3950X and 3900X versus Ryzen 9 3900XT; Ryzen 7 3800X versus 3800XT; and Ryzen 5 3600X versus 3600XT.

In single-threaded testing, however, all Ryzen 3000 XT models outpaced their closest Ryzen 3000 X-series equivalent by a solid 5 percent to 10 percent.

The big upset here was the Ryzen 5 3600X versus Ryzen 5 3600XT.

Within the Ryzen 9 / Core i9 bracket, the Ryzen 9 3950X still dominates multithreaded tests handily—with the exception of Time Spy CPU, which does not scale beyond 10 threads.

Loosely speaking, the top Core i7 or Ryzen 7 SKU is about 75 percent as fast as the Ryzen 9 3900XT, and the top Core i5 or Ryzen 5 SKU is about half as fast as the 3900XT.

The new Ryzen 3000XT CPUs aren't particularly exciting buys in and of themselves.

They're debuting at the same prices set for their original Ryzen 3000X counterparts—but unlike the first Ryzen 3000 series launch, they don't represent a groundbreaking performance improvement in any aspect, and they don't really change AMD desktop CPUs' relationships to their Intel counterparts.

Unfortunately for Intel, the 10th-generation Core CPUs still consume significantly more electricity and generate more heat than their Ryzen counterparts—a careful shopper willing to tolerate a 5-10 percent drop in Cinebench or Geekbench scores might still balk at the increase in power consumption.

This nearly 50 percent increase in power consumption for Intel versus AMD comes despite the fact that our Intel test system ran on integrated graphics only, while our Ryzen system is running on a Geforce RTX 2060 Super—and a PCI Express 4.0-capable motherboard.
