AMD today expanded its Ryzen 9000X3D line of Socket AM5 desktop processors that combine the "Zen 5" microarchitecture with 3D V-Cache technology, with the introduction of two high core-count models, the Ryzen 9 9950X3D and the Ryzen 9 9900X3D. The 9950X3D is a 16-core/32-thread chip, while the 9900X3D is 12-core/24-thread. These are dual-CCD processors, and much like the Ryzen 9 7000X3D, the 3D V-Cache is only present on one of the two CCDs, while the other is a regular CCD with just the 32 MB on-die L3 cache. There is one key difference, though. Since AMD has redesigned 3D V-Cache for "Zen 5" to be below the CCD and not above, the CCD with it has the same clock speed boosting characteristics as the CCD without 3D V-Cache; and AMD has worked to refine its software-based OS scheduler optimization such that productivity applications favor either of the CCDs, while games stick to the one with 3D V-Cache.

The Ryzen 9 9950X3D comes with a base frequency of 4.30 GHz, and boosts up to 5.70 GHz, with a 170 W TDP. This is much higher than the 5.20 GHz maximum boost frequency of the Ryzen 7 9800X3D, which makes the 9950X3D the company's fastest gaming desktop processor. The Ryzen 9 9900X3D is similarly interesting—you get a base frequency of 4.40 GHz, and 5.50 GHz maximum boost frequency, which is higher than that of the 9800X3D, although the CCD with the 3D V-Cache only has 6 cores. The 9950X3D should hence end up beating the 9800X3D in gaming workloads, while the 9900X3D should be either on par or slightly slower than the 9800X3D at gaming, although faster than any chip from the non-X3D Ryzen 9000 series.
