As you know, the Ryzen 9000X3D series features a dual-CCD design, similar to the Ryzen 7000X3D series, with a 3D V-Cache strapped to a single CCD. This time around, AMD is putting the so-called 2nd Gen 3D V-Cache below the CCD, rather than above it, allowing the CCD to retain the same boost clocks as the CCD without the V-Cache. On the software side, AMD has tuned the scheduler in order for production applications to use both CCDs, while games should prefer the one with the 3D V-Cache.
As said, AMD is launching two SKUs, the Ryzen 9 9950X3D and the Ryzen 9 9900X3D. The Ryzen 9 9950X3D is a 16-core/32-thread SKU with a base frequency of 4.3GHz, boosting up to 5.7GHz. It has a TDP of 170W, and the total cache amounts to 144MB. The Ryzen 9 9900X3D is a 12-core/24-thread SKU, which means that AMD has cut the CCD with 3D V-Cache down to 6 cores, leaving it with a total of 140MB of cache and a much lower 120W TDP.
According to AMD's own slides, the flagship Ryzen 9 9950X3D is about 8 percent faster than the Ryzen 9 7950X3D and beats the Intel Core Ultra 9 285K processor by around 20 percent in gaming. When it comes to productivity, those percentages go to 13 and 10 percent, respectively.
Both SKUs will be available in Q1 2025, according to AMD.
