AMD Ryzen 9 7900X3D Review

You are currently viewing AMD Ryzen 9 7900X3D Review

AMD’s $599 12-core AMD Ryzen 9 7900X3D is built to compete with Intel’s Core i9-13900K, which it outperforms in gaming by an average of 7%, demonstrating its superiority. AMD, however, has been unusually quiet about this model; the firm neither provided a sample to the press nor any of the customary pre-launch benchmarks we’ve come to expect.

The extremely excellent flagship 16-core Ryzen 9 7950X3D, which has seized the title of the fastest gaming CPU on the market and the greatest CPU for gaming on the highest-end rigs, may be the reason why AMD’s own AMD Ryzen 9 7900X3D is AMD’s biggest rival. 

The AMD Ryzen 9 7900X3D, like its more expensive sibling, uses AMD’s novel second-gen 3D V-Cache to increase L3 capacity to a massive 128MB, increasing gaming performance to previously unheard-of levels. While there are some compromises in other areas of work, the AMD Ryzen 9 7900X3D is designed primarily for gamers who want to smash through CPU-limited games and yet offers 12 cores to cope with demanding productivity applications. 

AMD Ryzen 9 7900X3D Overview & Specifications

The introduction of their 3D V-Cache technology, which we originally saw on the Ryzen 7 5800X3D, is the primary difference between the original 7000 series Ryzen 9 CPUs and the new X3D variants. We anticipate some amazing outcomes because the newest Ryzens are obviously much more powerful in terms of core count and clock speed.

A high-performance CPU with great specs is the AMD Ryzen 9 7900X3D. It has remarkable processing capacity with 12 cores and 24 threads, making it a great option for demanding activities like video editing, 3D modeling, and scientific simulations.

Each chiplet of the AMD Ryzen 9 7900X3D has six active cores, according to AMD, guaranteeing a balanced design across the CPU. This avoids any unbalanced configurations, such as one chiplet having 8 cores with 3D V-Cache while the other only has 4 cores without it.

Even though the sale embargo is about to be lifted in a few hours, the 7900X3D hasn’t received much attention from critics. It will be more difficult for gamers to choose between the AMD Ryzen 9 7900X3D, 7900X, 7700X, or 7600X SKUs as a result of this. Whether it was a tactical choice or not, AMD’s decision to not restrict the availability of 7900X3D samples has not made this decision any simpler.

The company’s future “Zen 4” CPU has their ground-breaking 3D Vertical Cache technology, significantly enhancing gaming performance.

With this technology, one of the two CCDs in these processors has a 32MB on-die L3 cache that is supplemented by a 64MB SRAM die. The combined 96MB cache significantly reduces computational latencies, especially for gaming. Users may anticipate better gaming experiences, quicker processing times, and overall greater system performance with this upgraded cache.

Even without any particular scheduling behavior in the Linux kernel around these AMD Ryzen 9 7900 series X3D components, where one CCD is cache optimized and the other frequency tuned, the AMD Ryzen 9 7900X3D (and 7950X3D) continue to operate well on Linux. The two of these CPUs have so far performed admirably in my Linux tests. Even for applications that cannot benefit from big cache sizes, the AMD Ryzen 9 7900X3D reduced power demand results in some good power efficiency advantages.

Recall that the AMD Ryzen 9 7900X3D has 12 cores and 24 threads, a base speed of 4.4 GHz, a boost clock of 5.6 GHz, an L1 cache of 768 KB, L2 cache of 12 MB, and L3 cache of 128 MB through 3D V-Cache. The 7900X3D has a 120 Watt TDP, much like the 7950X3D. In contrast, the Ryzen 9 7900X (non-3D) has a default TDP of 170 Watts, a base clock speed of 4.7 GHz, a maximum boost speed of 5.6 GHz, and an L3 cache capacity of 64 MB.

Although there are presently just a few publicly accessible benchmarks for the AMD Ryzen 9 7900X3D, our analysis of the existing data shows that this CPU performs admirably. As anticipated, it acts as a fantastic compromise between the entry-level 7800X3D and the expensive 7950X3D. The 7900X3D is still a good choice for consumers wishing to purchase a high-end CPU for less than $600 even though its performance might not be as impressive as that of its bigger sister.

The gap between the AMD Ryzen 9 7900X3D and the Intel i9-13900K has been closing in recent benchmarks, and this has helped to reduce the performance difference between the two processors in this price bracket. AMD consumers might anticipate a better future with this 7000 series generation with such comparable performance. Additionally, AMD has once again surpassed Intel to claim the title of top gaming CPU on the market.

AMD Ryzen 9 7900X3D Conclusion

In summary, the AMD Ryzen 9 7900X3D is a potent CPU that has the cutting-edge 3D V-cache technology and provides respectable performance. It may not be as powerful as the top-tier Intel i9-13900K or KS, but it is still a great option for those looking to get a high-end CPU at a low cost. However, for those on a tight budget, the 7900X3D is still a terrific choice that won’t let them down too badly. If at all possible, we suggest clients to get the 7950X3D.

Overall, AMD has made tremendous progress with the Ryzen 9 7900X3D, which will appeal to both power users and gamers.
