The Ryzen 7 3800XT is an 8-core/16-thread processor with a base clock of 3.9GHz and a max boost clock of 4.7GHz, which is 200MHz higher than the original 3800X.

The Ryzen 9 3900XT is a 12-core/24-thread processor with a base clock of 3.8GHz with a max boost clock of 4.7GHz, which is a 100MHz increase over the original Ryzen 9 3900X.

AMD claims these new processors can maintain boost frequencies for somewhat longer durations as well, which should offer an additional performance uplift, based on refinements made to the chip's 7nm manufacturing process.

It said that in testing, the new CPUs offer small performance gains over their "non-XT" namesakes, with 100MHz - 200MHz increases in boost clocks resulting in roughly two to five percent increases to both their single and multi-threaded performance in most workloads. Those frequency increases come at the expense of slightly higher peak power consumption as well of course.

The best news may be that AMD's original Ryzen 5 3600X, Ryzen 7 3800X, and the Ryzen 9 3900X will remain in the line-up for the time being, but their prices will be slashed a bit, with the new Ryzen 5 3600XT, Ryzen 7 3800XT, and Ryzen 9 3900XT arriving with the same $249, $399, and $499 introductory prices as the originals.
