There is no doubt that in the PC, the freedom to choose the components allows us to build systems adapted to our budget and our needs. The problem comes when you want something that performs well and the differences between one chip and another might seem insignificant on paper or unimportant, but once the notion of performance versus price comes into play, the whole tower of mud crumbles. This is when it is important to know how to choose well.
Add more cache, a safe bet on performance
After the release of the AMD Ryzen 7 7800X3D, consisting of a single CCD and therefore with all cores benefiting from the V-Cache, the 5800X3D finally has its real successor on the market. Although, as we have said many times, the benchmarks do not perform better on a CPU with much more last-level cache memory, in general applications it does, and we have already been able to verify this with the 5800X3D, which with this small change was able to match the Ryzen 7700X in most workloads.
On the other hand, it is no secret that RAM access speed is the biggest bottleneck. It is therefore a safe bet for any processor to overcome this problem and the addition of cache memory is the safest and most classic of all. Of course, the common user is not interested in these details of how, but what and precisely what is Caesar, although we criticize AMD for what it does in graphics cards, in processors, it is a totally different song.
AMD Ryzen 7 7800X3D is the best CPU for gaming
Not too long ago the folks at Techpowerup decided to do a mock review of the Ryzen 7 7800X3D using the Ryzen 9 7950X3D for it. Since the two CPUs are identical except for the addition of a CCD without V-Cache in Ryzen 9, they decided to disable it to have their little brother on the practical side. Of course, the Boost speed of AMD’s balanced eight-core processor is slightly lower than asymmetrical sixteen of the same brand, but most likely with a slightly higher base clock speed.
On the face of it, losing 8 cores is losing performance, however, the fact that there’s higher latency between them since they’re on another chip and they perform worse because they don’t have not V-Cache is counterproductive. On the other hand, there is not a single game currently, in the PC world, that requires more than 8 cores and 16 threads to run properly and less if they have improvements.
The reality in numbers
Now the best stress benchmark for a CPU is to run it across the country that means it doesn’t sit still for a while and the best graphics card for that is the RTX 4090 it’s so fast that it forces you to all processors have to keep pace or general performance, in frame rate, it’s cut. Well according to these tests, by activating or deactivating CCD0 (that of the V-Cache) or CCD1, the results in games are surprising.
| Processor | 1080p (Full HD) | 1440p (Quad HD) | 2160p (4K) |
|---|---|---|---|
| AMD Ryzen 9 7950X | 100% | 100% | 100% |
| AMD Ryzen 9 7950X (CCD0 idle) | 86.5% | 90.4% | 96.2% |
| AMD Ryzen 9 7950X (CCD1 idle) | 102.1% | 103% | 100.2% |
| Intel Core i9-13900K | 100.2% | 102.3% | 100.8% |
The Ryzen 7 7800X3D would be equivalent to the 7950X3D with the CCD1 off, since games never use the extra 8 cores, we find that removing it from the equation not only doesn’t decrease performance, but also because it there are no associated latencies. under the same chip, the performance increases slightly, even if it is only 2 or 3% depending on the load level.
We must not forget that a higher frame rate per second is a huge burden on the CPU, which is why in Full HD the absence of V-Cache weighs on the benchmarks when CCD0 is disabled in the BIOS for keep the one with less performance. Si bien con ninguno de los procesadores de la lista deberíamos tener problems, si hablamos de gastar de más para tener una potencia por encima de la media, no solo en juegos, sino en diversas aplicaciones, entonces está muy claro cuál es el procesador más prometedor from the moment.
Why this will be the best gaming CPU in years
We highly doubt the more capable i9-13900KS will overclock, even though it manages to hit 6GHz on Boost on paper. Rather, it’s the Intel chip that’s under tremendous pressure to outperform the 7800X3D in games. However, if we look at the roadmap for the future, especially in the short to medium term, we don’t see anything from AMD or Intel that makes this CPU a rival that will knock it off the pedestal as the best games processor in a long time.
