Multiple speculations have focused on a CES 2025 launch for AMD's Ryzen 9 9950X3D and Ryzen 9 9900X3D, which would complete the introduction of high-end Zen 5 desktop processors. Earlier, there was a suggestion that both models would feature a 3D V-cache tile on each CCD. However, it appears this may not be true.
Cache Details
Well-known leaker @AnhPhuH has mentioned that the Ryzen 9 9950X3D and Ryzen 9 9900X3D will inherit the same L3 cache as seen in the previous generation (Ryzen 7000) models. While it’s a letdown that there won't be additional cache, these CPUs will likely have a reversed cache tile layout. This design should enable you to overclock your CPU effectively. Typically, Ryzen 9 models are more amenable to overclocking than Ryzen 7 ones, and this should hopefully also apply to the X3D versions.
Release Timeline
The leaker further states that both CPUs are expected to be available by the end of January 2025. In the past, the Ryzen 7 7800X3D outperformed the Ryzen 9 series, leading to questions about whether AMD has made changes to ensure better performance with the Ryzen 9 9950X3D and Ryzen 9 9900X3D. Only time will give us the answers. On a different note, Intel's not-so-great Arrow Lake-S launch means that AMD is really just competing with itself this time around.
