AMD launches new generation processors Ryzen With Zen 4 architecture and support for new DDR5 and PCI Express 5.0 technologies. new ones Ryzen 9 7900X and 7950X they are the two best devices with similar configurations, the main differences are the number of cores and above all the price.
while Ryzen 9 7900X Slightly more modest with “only” 12 cores and 24 threads 7950X It has 16 cores and 32 threads. The models come with suggested prices of R$4,199.99 and R$5,499.00 respectively.
Because they have similar specs, it’s important to understand how the new AMD CPUs compare and whether their performance justifies such a significant difference in launch price.
Ryzen 9 7900X and 7950X Specifications
The new Zen 4 architecture processors feature 5nm microarchitectures for the cores and 6nm for the CPU I/O die, and use TSMC’s FinFET fabrication process. Both models are currently available and the suggested price difference between them is R$1,300 in Brazil. It is worth remembering that the retail price can be very different and depends on each store.
In addition to prices, frequencies, cores/threads, and cache also differ. According to the data provided by AMD itself, all other elements are the same.

| Thread | 32 | 24 |
| Base Frequency | 4.5GHz | 4.7GHz |

The thermal design of the new CPUs is also the same, with a TDP of 170W, much higher than 105W. Ryzen 5900X. High-end and enthusiast models don’t come with a heatsink, so adding a solid thermal solution is necessary to meet this demand.
Both processors are unlocked, support Precision Boost 2, AMD EXPO memory overclocking technology, and are compatible with X670(E) and B650(E) chipsets. This is the first generation of AMD socket processors. AM5The 2016 AM4 socket is definitively deprecated.
So far, all approved motherboard chipsets only support DDR5 memory, and this switch will inevitably make the upgrade quite expensive. Anyone who wants to participate in this way Ryzen 7000 you will have to replace the complete kit as it is not a transitional generation.
performance comparison
whereas Ryzen 9 7900X and 7950X they have so many similarities that the difference in performance between them should justify the extra investment. In Cinebench R23 Multi Core, the enthusiast CPU score hit 38,165 against 29,358. 7900X. Both were better than the Intel Alder Lake Core i9-12900K.
In file management tests, Ryzen 9 7950X it is also the leader of the score in all cases, with margins ranging from 12% to 45%. Interestingly, in the specific decompression test, 5950X still beating 7900X.
However, in most other synthetic tests, the difference between AM5 processors is quite small. Even in heavy applications like Adobe After Effects 2022 and Adobe Premiere Pro 2022, 7950X was not significant enough to represent a significant gain in productivity.
The biggest advantage of the new 16-core, 32-thread home processor was the compilation time for Chromium codes, with an advantage of over 10 minutes for the 12900k, 5950X and 5950X. 7900Xwhich gives very similar results.
gaming performance
An important consideration in gaming performance is that most games don’t take much advantage of the processor’s core count. In general, this affects performance more when simultaneously using other applications such as capture software, broadcasts, communication programs or streaming services.
Therefore, it is natural for results to appear. Ryzen 9 7900X and 7950X very similar both between the two models and when compared to other processors. Intel’s Alder Lake CPUs fared better than the new AMD processors in most frame-per-second comparisons, but less than 10 FPS doesn’t matter outside of the esports scene.
The new AMD CPUs averaged 213 frames per second. Despite the excellent result, this is not something that counts in favor of the enthusiast model for the majority of users.
Performance Per Watt and Cooling
The most relevant point in the comparison between new CPUs is system consumption. Even if they have similar characteristics and the same thermal design, Ryzen 9 7900X consumes an average of 50 W less. 7950Xmakes it much more energy efficient.
According to tests, the new architecture brings a working change that may annoy users who are worried about the temperatures of their systems. As with chips for laptops, Ryzen 7000 It is designed to operate at its thermal limits during heavy use.
This means that whenever the processor is doing heavy operations, the system will operate within the safe limit of 95ºC, adjusting voltages and frequencies according to the cooling capacity of the system.
As an answer Technology Point In this regard, AMD stated that this design is on purpose, as this temperature is not only safe, but ideal for getting the most out of the new silicon. As a result, choosing a quality cooling kit is more critical to performance than simple overclocking setups.
When is Ryzen 9 7950X recommended?
BRL more than 1300 for standard user Ryzen 9 7950X Investing in a DDR5 memory kit or a more robust motherboard with more expansion options will be much more rewarding.
On the other hand, it is worth paying attention to the fact that the suggested price does not always reflect the retail price, especially if you want to set up a system for multitasking activities. More cores/threads 7950X they may not make a difference in a player setup, but depending on the final price, they can represent a productivity gain for content creators or those working with editing and creation software.
