Ryzen 7950X3D with 5.9 GHz OC does not improve gaming performance
We already have before us the reviews of the expected Ryzen 7000X3D. In fact, we already published a review on the web where we could see the gaming performance and low power consumption of the 7950X3D. In the end, the expectations were so high that for some users the improvement in gaming performance is not as great as AMD had announced. But don’t worry, because these processors can squeeze more. Even though they were going to have a very limited overclockthey have already achieved that a Ryzen 9 7950X3D scope 5.9GHz and we will see if he performance increase it’s worth it.
When AMD announced the future Ryzen 7000X3D, PC gamers started to get interested in a platform change. Considering that the Ryzen 5800X3D gave such good results in gamesIf the next generation offered such an improvement, it was clearly going to outsell regular CPUs. However, when the performance numbers began to trickle in, we saw that many games barely managed a 5 or 10% at most over the i9-13900K. In fact, in several titles the new Ryzen 9 7950X3D lags behind Intel again.
We can overclock the Ryzen 7950X3D with PBO2 and Curve Optimizer
The new Ryzen 7000 equipped with 3D V-Cache have not been the revolution that was expected of them, but if we leave behind the raw power, we see a great energy efficiency. AMD has shown how it is capable of competing head to head against the i9-13900K consuming less than half with its Ryzen 9 7950X3D 16 core. That is where we can say that the processor stands out, consumes less and it is cooler than the Ryzen 7950X. This makes them perfect for overclocking to increase your frequencies and performance. However, we found what we expected: AMD has limited the OC of these chips.
This does not mean that it is not impossible to raise the frequencies, since SkatterBencher has managed to do Overclock your Ryzen 9 7950X3D to 5.9 GHz. For the most curious, we leave you the entire process that has followed and its results. As a summary, the new Ryzen 9 7950X3D has an overclock limit of 5.250MHz and 1.2V in its CCD0, where the 3D V-Cache is. Instead, in the CCD1 without the extra cache, we can go up to 5.750MHz and 1.4V. To perform the overclock you can follow several ways, but we must go to use PBO2 and Curve Optimizer(CO), which in this case has been left with a -27 CO average.
The 5.9 GHz 7950X3D hardly improves its performance in games and applications
If you have a Ryzen 5000 or 7000 you will know both overclock methods, because with them we can optimize the voltage/frequency curve of these processors. With this we see a clear improvement if we look at the graphs and when measuring the frequencies we see how they increase by about 150 to 200MHz. But there is still one more method to slightly increase these and achieve somewhat better performance. We will achieve this through eclk (External Clock Generator), which increased to 105MHz.
With this last overclock method done, we can finally see a performance comparison between Stock and Overclock. As we can observe, do OC to the Ryzen 7950X3D is not worth itSo we’ll get a 10% improvement at best with Geekbench Multi Core. In fact, we’re surprised to see how little Cinebench or V-Ray improves, considering they’re rendering benchmarks. As to gameshe performance is pretty much the same with overclock. Regarding the differences of frequency and consumption in Prime 95:
- From the factory with Prime95 and AVX512 disabled we have 134.2W with 4,553 MHz and 81.5°C.
- With the overclock done by ECLK, PBO and CO, it consumes 152.1W with 4.592 MHz and 83.3°C.
