AMD announces Ryzen 7000X3D processors: the flagship Ryzen 9 7950X3D will receive 144 MB of cache memory

AMD has finally announced the long-awaited line of Ryzen 7000X3D processors with a large additional 3D V-Cache buffer. Despite previous rumors and fears that the upcoming series may consist of only one model, as was the case with the Ryzen 7 5800X3D, this time the developers will offer three chips with a radically increased L3.

The line will be headed by a 16-core Ryzen 9 7950X3D with a frequency formula of 4.2/5.7 GHz, a total cache memory capacity (L2+L3) of 144 MB, and a declared TDP of 120 W. The figures are impressive, considering that the Ryzen 9 7950X base model has a similar frequency configuration – 4.5/5.7 GHz, a total buffer of 80 MB, and a TDP of 170 W. As you can see, the peak frequencies remained at the same level.

Let’s assume that during the maximum multi-threaded load, the level will be 100-200 MHz lower, which in turn made it possible to immediately reduce the thermal package by 50 W. And this is despite the additional L3 buffer. Indeed, as practical experiments show, the ability to configure Precision Boost Overdrive (PBO) allows you to balance the parameters of the chips on Zen 4, taking into account your needs. CPU power consumption can be significantly reduced with minimal loss in performance.

As for the capabilities of the Ryzen 9 7950X3D, the developers claim a significant advantage over the Core i9-13900K. Depending on the task, the novelty must be ahead of the opponent by 4–52%. Very significant values, which probably cannot be compensated even by the announced Core i9-13900KS with an increased peak frequency of up to 6 GHz.

Gaming performance is also potentially on the side of AMD’s expected novelty. In certain projects, the advantage over the Core i9-13900K is 13–24% in Full HD mode with high image quality. Unbiased comparative measurements of these models will still be more than enough after the official start of Ryzen 7000X3D sales, but so far the indicators from AMD look optimistic.

Ryzen 9 7900X3D with 12 cores also received a very aggressive frequency formula – 4.4/5.6 GHz. The total capacity of the L2 and L3 buffers in this case is 140 MB, and the TDP is also declared at 120 W.

But in the case of the Ryzen 7 7800X3D octa-core processor, the operating frequencies of the model with 3D V-Cache are slightly lower than those of the model without an additional buffer. The basic level has not yet been determined by the developers, the slide indicates 4.X MHz or even “Boost”, while the maximum acceleration is 5 GHz. At the same time, the classic Ryzen 7 7700X has a formula of 4.5/5.4 GHz. However, the power of the Ryzen 7 7800X3D is not in the frequencies at all. The processor has a total L2+L3 buffer of 104 MB at a TDP of 120 W.

The presentation slide shows the relative performance of the Ryzen 7 7800X3D compared to the Ryzen 7 5800X3D. The novelty has an advantage of 20-30% over the gaming flagship of the previous generation. This is a very noticeable acceleration, considering the sometimes surprising performance of the first model with 3D V-Cache. It is interesting that in the presence of older models, the term “The New Ultimate Gaming Processor” is used for the Ryzen 7 7800X3D.

The developers revealed an interesting detail regarding the general layout of the Ryzen 7000X3D. After it became clear that in the new series, there will still be models with an additional buffer that will have more than 8 cores. Of course, in this case, two 8-core CCD crystals (Core Complex Die) are used. But only one of the two CCDs is equipped with an additional 3D V-Cache buffer with a capacity of 64 MB. This explains both the total capacity of cache memory in older models (140 and 144 MB) and the ability to keep operating frequencies at a high level. Obviously, the cores located in the CCD without an additional layer in the form of 3D V-Cache are accelerated to the maximum.

Those who want to buy new processors will have to wait a little longer. The start of sales of Ryzen 7000X3D chips is scheduled for February. AMD has not yet announced the exact date and recommended prices of models with 3D V-Cache.
