Last night we finally found out about the next generation of AMD 7000X3D processors that will land in February. While we thought we would only have one CPU, it is actually three processors that will be launched in February with the Ryzen 9 7950X3D and 7900X3D as well as the Ryzen 7 7800X3D. To put it simply, this series of 7000X3D processors benefits from a “3D V-Cache” which is materialized by the addition of 64 MB of L3 cache.
These processors are mainly intended for gaming and e-sport type competitive games in 1080p and 1440p. The idea is to ensure a maximum of FPS or in any case, the maximum of FPS in a constant way. AMD aims to offer the best performance, especially against the next i9-13900KS.
The series consists of three CPUs: the Ryzen 7 7800X3D with 8 cores/16 threads, the Ryzen 9 7900X3D with 12 cores/24 threads and the Ryzen 9 7950X3D with 16 cores/32 threads. The 7800X3D comes with a base frequency not yet defined by AMD as well as a boost up to 5.00 GHz. The 7900X3D has a base frequency of 4.40 GHz and a Boost up to 5.60 GHz. Finally, the top of the range represented by the 7950X3D operates at 4.20 GHz and a Boost that can flirt with 5.70 GHz.
A little reminder about the architecture:
If you haven’t yet read our article about the new Ryzen 7000X test, now is the time to check it out. The new Ryzen 7000 see the amount of L2 cache doubled, from 512KB to 1MB of L2 cache per core, compared to the previous generation (Ryzen 5000). On the other hand, there is no change in the amount of shared L3 cache memory, which remains at 32 MB per CCD. Here is a representation of the internal architecture of our Ryzen 9 7950X.
If we calculate the amount of L2 and L3 memory for our 7950X, we are at 16 MB of L2 since 16 cores + 2 x 32 MB of L3 (CCD0 + CCD1), which gives us a total of 80 MB. If you do the same calculation for the 7900X, you get 76 MB.
If we look at the specifications of the Ryzen 9 7950X3D, we have the original 80 MB of the processor + the 64 MB of L3 cache (3D V-Cache), which gives us a total of 144 MB. The 7900X3D will go from 76 to 140 MB (L2+L3) and the 7800X3D from 40 to 104 MB.
There remains however an unknown, it is the way in which is implemented this “3D V-Cache”. Knowing that the 7800X3D has only one CCD, the 64 MB are therefore implemented on it. The Ryzen 9 7950X3D and 7900X3D would then also see a similar integration, which would mean that only one CCD benefits from the “3D V-Cache” technology and the other one is without it. When the cores are used for gaming, it is the CCD with the “3D V-Cache” solution that would be used. The idea would be to reduce the TDP but also to make savings. We hope to have a clarification in the coming hours but one thing is certain, these Ryzen 7000X3D processors have not finished talking about them and we impatiently await their arrival in February!
