Zen 4 with 3D Cache: AMD Ryzen 9 7950X3D, Ryzen 9 7900X3D, and Ryzen 7 7800X3D reportedly breaking cover at CES 2023

We reported last week that AMD might launch the Zen 4 SKUs with 3D V-Cache early next year. The CPUs, which included the Ryzen 9 7950X3D and the Ryzen 7 7800X3D, were suggested to be available on store shelves in Q1 2023. We now have more information regarding the release date and possible SKUs of Zen 4 with 3D cache.

According to reliable leaker Greymon55, AMD will announce the 3D cached versions of the Zen 4 Ryzen processors at CES 2023. Unlike previous leaks, there will also be a Ryzen 9 7900X3D in addition to the Ryzen 9 7950X3D and the Ryzen 7 7800X3D.

AMD’s first chip with 3D stacked cache, the Ryzen 7 5800X3D, offers a significant gaming performance bump over the top-of-the-line Zen 3 Ryzen 9 5950X. It even beats the Intel Core i9-12900K in many scenarios. Assuming AMD manages to achieve a similar gain over the vanilla Zen 4 parts, we are in for a treat as, per the company’s testing, even the midrange Ryzen 5 7600X can keep pace with the Core i9-12900K in gaming.

Furthermore, Greymon55 thinks that the US$799 price tag seems more likely for the Ryzen 9 7950X3D. As for the Ryzen 7 7800X3D and the Ryzen 9 7900X3D, they will undoubtedly cost more than their non-3D counterparts.

We can see that there is a US$150 difference between the Ryzen 7 7700X (US$399) and the Ryzen 9 7900X (US$549) and a further US$150 delta between the Ryzen 9 7900X and the Ryzen 9 7950X (US$599). As such, the Ryzen 7 7800X3D can slot nicely between the non-3D Ryzen 7 and the Ryzen 9 SKUs while the Ryzen 9 7900X3D can fit in between the Ryzen 9 7900X and the Ryzen 9 7950X.

That said, all of this is pure speculation. We’ll have to wait and see how AMD positions the Zen 4X3D chips and whether or not the CPUs can exceed the performance afforded by the base Zen 4 processors and the Intel Raptor Lake CPUs.
