With the release of the new AMD X3D series, a lot of people are wondering if the Ryzen 9 7900X3D is better than the 7900X and if it’s worth the extra $50 for the new CPU. In this article, we’ll be breaking down the bout of the Ryzen 9 7900X vs Ryzen 9 7900X3D and provide a full comparison so you can make up your mind.
To start with the most important stuff: what is AMD’s 3D V-cache? AMD 3D V-Cache is a technology introduced with the AMD Ryzen 7 5800X3D processor. It is a high-density cache memory built on a 3D packaging technology, designed to improve CPU performance by reducing memory latency.
The AMD 3D V-Cache uses high-speed, low-latency vertical connections between multiple layers of the DRAM cache and the processor die. This technology enables the cache memory to be stacked on top of the processor, reducing the distance that data needs to travel between the processor and cache memory. As a result, data can be retrieved and processed faster, leading to improved performance and responsiveness.
The AMD 3D V Cache has a capacity of up to 64 MB, which is significantly larger than traditional on-chip CPU caches. This extra cache memory can improve performance in applications that require a lot of data to be accessed quickly, such as gaming, video editing, and 3D modeling.
Ryzen 9 7900X vs 7900X3D: Specs
The Ryzen 9 7900X3D and Ryzen 9 7900X are both high-end desktop processors from AMD, both based on the Zen 4 architecture and manufactured on the TSCM 5nm process node.
In terms of core and thread count, both CPUs have 12 cores and 24 threads, which means they are both capable of handling demanding workloads such as video editing, 3D modeling, and other productivity tasks.
The Ryzen 9 7900X3D operates at a base clock speed of 4.4GHz and a boost clock speed of 5.6GHz, which is slightly lower than the Ryzen 9 7900X’s base clock speed of 4.7GHz. However, both CPUs have the same boost clock speed of 5.6GHz, which is impressive and makes them both highly capable processors for demanding tasks.
| Specs | Ryzen 9 7900X3D | Ryzen 9 7900X |
|---|---|---|
| Architecture | Zen 4 | Zen 4 |
| Process node | TSCM 5nm | TSCM 5nm |
| Cores/Threads | 12 / 24 | 12 / 24 |
| Frequency | 4.4GHz | 4.7GHz |
| Boost clock speed | 5.6GHz | 5.6GHz |
| Socket | Socket AM5 | Socket AM5 |
| Cache L3 | 128MB | 76MB |
| TDP | 120W | 170W |
| Launch MSRP | $599 | $549 |
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.
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.
Lastly, the Ryzen 9 7900X3D is priced at $599, which is slightly higher than the Ryzen 9 7900X’s launch MSRP of $549. This price difference may be attributed to the larger cache size of the Ryzen 9 7900X3D and its lower TDP.
Overall, both CPUs are highly capable processors with impressive performance, but the Ryzen 9 7900X3D offers a larger cache size and lower TDP, which may make it a more attractive choice for users who prioritize energy efficiency and performance.
Ryzen 9 7900X vs 7900X3D: Performance
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.
Although the Ryzen 9 7900X3D and the Ryzen 9 7900X have the same maximum clock speed when boosted, the latter has a higher base clock speed of 4.7GHz compared to the former’s 4.4GHz. This means that the Ryzen 9 7900X may outperform the Ryzen 9 7900X3D at lower clock speeds.
However, the Ryzen 9 7900X3D is more energy-efficient at these lower speeds, making it an attractive option for gamers looking for a powerful and efficient CPU. Additionally, the Ryzen 9 7900X3D has a lower TDP than the Ryzen 9 7900X, further contributing to its efficiency.
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
The initial cost of the Ryzen 9 7900X3D is $599, but as with the launch of its predecessor, the 7900X, it is likely that the price may decrease in the months following its release. The 7900X was originally priced at $549 but can now be purchased for around $450 with some searching, making it a more attractive option. Both CPUs provide excellent value for money considering their impressive capabilities.
If you come across a significantly discounted Ryzen 7900X from a reliable seller such as Newegg, it may be a good idea to take advantage of the deal since it’s uncertain if the newer 7900X3D will undergo price reductions anytime soon.
Ryzen 9 7900X vs 7900X3D: Conclusion
It’s important to note that both the Ryzen 9 7900X and the Ryzen 9 7900X3D are not meant for those on a tight budget. These CPUs are designed for those who demand top-of-the-line performance and are willing to pay a premium for it.
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.
Ultimately, it’s important to consider your individual needs and budget before making a decision between these two CPUs. While they both offer excellent value for the price given their impressive specs, it’s up to each user to decide which one is the best fit for their specific use case.
