AMD plans to announce its Zen 4 3D V-Cache processors at CES 2023. According to @quasarzone, there will be three variants of the next-gen X3D design: the Ryzen 7 7800X3D, the Ryzen 9 7900X3D, and the 7950X3D. They will feature eight, twelve, and sixteen cores like their planar variants. The second-generation V-Cache technology will offer significantly more on-die bandwidth, but the buffer size should remain unchanged.
The Ryzen 7 7800X3D will likely pack a 3D stacked cache die with 64MB of SRAM for a total of 100MB cache memory. The Ryzen 9 7900X3D could either feature two 64MB cache dies or a single denser cache die with 128MB of SRAM. Furthermore, the clock speeds of the Zen 4 X3D chips will be the same or close to their vanilla variants.
Alright, @quasarzone shared about Zen4 X3D info. Let’s summarize it:
They shared 3 exclusive Zen 4 3D info.
1) Three Ryzen 7000X3D model is confirmed. 16/12/8C. But about 8C model, it isn’t determined model name whether 7700X3D or 7800X3D
2) Unlike Zen 3 3D, clock speed will be same or at least almost same.
3) It is expect Jan 23. So CES.
From this point on, these are guess based on exclusive info.
R7 5800X is fixed at 4.4G, so can represent only 3D Cache difference.
Equally applied to the Ryzen 7000 series based on 5800X – 5800X3D perf improvements

Also, they shared about RX 7900 series stock.
Accoring to QSZ, early stock is extremely low. And we can see AIB model end of Q4.
For my think, low stock is about reference model. Maybe mostly will supply end of Q4 with AIB model?Originally tweeted by 포시포시 (@harukaze5719) on December 2, 2022.
Quasarzone has also shared the “estimated” benchmarks of the Ryzen 7 7950X3D:
Remember that these aren’t actual performance figures so take them with a grain of salt. The Ryzen 9 7950X3D is up to 33% faster than the Intel Core i9-13900K. Like its predecessor, the frame rates vary significantly from game to game. In the first one, it is 33% faster than the 13th Gen Core flagship. In the second, it beats the Raptor Lake lead by 15%, and in the third, by just 5%.
The Ryzen 7000X3D processors will hit retail shelves by the 23rd of January.
