Both processors belong to the same generation (Zen 4) and offer some impressive specs, but they have some differences that set them apart from each other. Starting with the core count, the Ryzen 9 7900X3D has 12 cores and 24 threads, while the Ryzen 7 7800X3D has 8 cores and 16 threads. This gives the Ryzen 9 a clear advantage in multitasking and running resource-intensive applications. Specs
In recent benchmarks, we have observed that the 7900X3D produces results that are closer to those of the Intel i9-13900K, thereby reducing the gap that existed between the two processors in this range. With such comparable performance, AMD users can look forward to a brighter future in this 7000 series generation. Furthermore, AMD has regained its title as the best gaming CPU in the market, edging out Intel once again. Ryzen 7900X3D: Conclusion As for the chip’s release date, now we know that it’s February 28th, it’s interesting that both Ryzen 9 X3D chips will arrive before the Ryzen 7 7800X3D debut, which was previously reportedly set for February 14th, before AMD denied that date while committing to February for the launch of the X3D. Finally, the TDP (thermal design power) of the Ryzen 9 is slightly higher than the Ryzen 7, with 128W compared to 120W. This means that the Ryzen 9 may consume a little more power under load. Ryzen 7 7800X3D vs Ryzen 9 7900X3D: Performance One important similarity the two CPUs share is their Zen 4 architecture. Zen 4 is incredibly powerful and capable of processing far more instruction per cycle than the previous Zen 3. It also made significant steps forwards in terms of energy efficiency, a step which perhaps proves vital to improving the performance of these two CPUs considering how power-hungry they both are. There is an upside though, namely that the 7900X3D boasts higher energy efficiency at those lower speeds. This is in line with the overall superior efficiency of the 7900X3D which has a lower TDP that the 7900X.We should start off by pointing out the obvious. Neither of these CPUs is budget-friendly. Instead, they offer some of the most powerful specs and stats available but expect to pay for them. The new chip manages to snatch the crown away from Intel in quite a few titles. In Gears Tacticsand Hitman 3, Intel was able to beat the base Ryzen 9 7950X, but the Ryzen 9 7950X3D is now here to defeat both processors. It leads in every game versus Intel and AMD, sometimes showing an improvement of up to 25% against the base version. However, Intel remains victorious in synthetic benchmarks and AI workloads. In terms of TDP, the Ryzen 9 7900X3D has a lower TDP of 120W compared to the Ryzen 9 7900X’s 170W. This means that the Ryzen 9 7900X3D should consume less power and generate less heat, making it a better choice for users who prioritize energy efficiency.
Another difference between these two CPUs is the amount of L3 cache they offer. The Ryzen 9 comes with a whopping 128MB L3 cache, which is significantly more than the Ryzen 7’s 96MB. This extra cache can boost performance in certain applications requiring more memory. Ultimately, the decision between the two will depend on your specific needs and budget. However, it is clear that both CPUs offer fantastic performance and are a testament to AMD’s continued innovation in the CPU market. We test Intel processors with the power limits fully removed for our standard measurements, so those chips run beyond the 'recommended' power settings but remain within warranty. We used DDR5 for both the Raptor Lake and Zen 4 processors. The cache is a critical component of a CPU as it acts as a storage space for frequently accessed data, which is essential for smooth gaming performance. The larger the cache size, the better the performance, and the 128MB cache size of the Ryzen 9 7900X3D is ideal for running programs at high levels without having to rely on the slower main memory. While we eagerly anticipate the release of the Ryzen 9 7900X3D, we can’t say for certain which CPU is the superior one just yet. However, based on the specs, it seems likely that the 7900X3D will outperform the 7900X due to its larger cache size. This cache acts as a storage space for frequently accessed data, which can greatly improve gaming performance. Despite the higher price tag, the improved performance may justify the investment for those who require the best possible performance in their gaming experience.In conclusion, the Ryzen 7 7800X3D and Ryzen 9 7900X3D are both excellent CPUs with impressive specs and performance. The Ryzen 7 7800X3D is a great option for gamers who want high performance at a more affordable price point, while the Ryzen 9 7900X3D is geared more towards professional users who need even more power for demanding tasks. We’ll be breaking down exactly what these differences mean in terms of performance later on in this article.
When it comes to cache size, the Ryzen 9 7900X3D has a larger L3 cache of 128MB compared to the Ryzen 9 7900X’s 76MB. A larger cache can help to improve performance by reducing the time it takes to access frequently used data. As you can see, when we put these two powerhouses head to head we see identical core and thread counts but not much else stays the same. Perhaps the standout difference is the Ryzen 9 7900X3D’s gigantic cache size, which comes into being thanks to its X3D technology. AMD has confirmed that each chiplet of the 7900X3D contains 6 active cores, ensuring a balanced configuration across the processor. This eliminates any uneven setups where, for instance, one chiplet would contain 8 cores with 3D V-Cache while the other has only 4 cores without it. And for any "mixed workload" users, single-core/lightly threaded boost isn't faster/higher on a regular R9 7950X vs the R9 7950X3D! While all-core boost won't be that much lower than the regular parts! (Think non-X Ryzen 7000 NOT R7 5800X3D).Overall, both CPUs are highly capable and powerful, and the performance difference between them is not significant. However, in high-end PC gaming, even the slightest advantage can make a difference, and the Ryzen 9 7900X3D’s larger cache size and energy efficiency make it a strong contender for gamers seeking optimal performance. Ryzen 9 7900X vs 7900X3D: Price AMD has just released its latest processor, the Ryzen 9 7900X3D, which is poised to take on the competition and set a new standard in performance. When the newest CPU from AMD goes head to head with the forthcoming budget option, seeing the Ryzen 7 7800X3D vs the Ryzen 9 7900X3D, comparisons are already proving to be contentious.
