There is no doubt that in the PC the freedom to choose the components allows us to build systems suitable to our budget and needs. The problem comes when we want something with high performance and the differences between one chip and another may seem insignificant on paper or unimportant, but once the concept of performance compared to price enters, the whole tower of mud collapses. It is at this point where it is important to know how to choose well.
Add more cache, a sure bet on performance
After the release of the AMD Ryzen 7 7800X3D, which is composed of a single CCD and, therefore, with all the cores benefiting from the V-Cache, the 5800X3D finally has its true successor on the market. Although, as we have said several times, the benchmarks do not get better results on a CPU with much more last-level cache memory, in general applications, yes, and we could already verify that with the 5800X3D, which with this small change was capable of to match the Ryzen 7700X in most workloads.
On the other hand, it is no secret that the speed of access to RAM is the biggest bottleneck. Therefore, it is a safe bet for any processor to alleviate 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 those details of how, but what and precisely what is Caesar’s, although we criticize AMD for how it is doing in graphics cards, in processors it is a totally different song.
The AMD Ryzen 7 7800X3D is the best processor for games
Not long ago, the folks over at Techpowerup decided to do a mock review of the Ryzen 7 7800X3D using the Ryzen 9 7950X3D for it. Since both CPUs are the same, except for the addition of a CCD without V-Cache in Ryzen 9, they decided to disable it to have their younger brother on a practical level. Of course, the Boost speed of AMD’s symmetrical eight-core processor is slightly less than sixteen asymmetrical of the same brand, but most likely with a slightly higher base clock speed.
At first glance, losing 8 cores is losing performance, however, the fact that there is a higher latency between them since they are on another chip and perform worse because they do not have the V-Cache is counterproductive. On the other hand, there is not a single game currently, within the PC world, that requires more than 8 cores and 16 threads to run smoothly and less if these have improvements.
The reality in figures
Now, the best stress benchmark for a CPU is to make it do a cross-country run, this means it doesn’t sit still for a while and the best graphics card for this is the RTX 4090, it’s so fast that it requires you to all the processors have to keep up with it or the general performance, in frame rate it is cut. Well, according to these tests, activating or deactivating CCD0 (the one from the V-Cache) or CCD1, the results in games are surprising.
| Processor | 1080p (Full HD) | 1440p (QuadHD) | 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 inactive, since games never use the 8 additional cores we find that removing it from the equation not only does not decrease performance, but also because there are no associated latencies As they are all 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 weight for the CPU, which is why in Full HD the lack of V-Cache weighs on the benchmarks when CCD0 is disabled in the BIOS to keep the which has less performance. Although we should not have problems with any of the processors on the list, if we talk about spending more to have above-average power, not only in games, but in various applications, then it is very clear which is the most promising processor. of the moment.
Why it will be the best gaming processor in years
We highly doubt overclocking the higher-performing i9-13900KS, even though it does manage to hit 6GHz on Boost on paper. It is rather the Intel chip that is under enormous pressure to outperform the 7800X3D in games. However, if we look at the roadmap for the future, especially in the short and medium term, we do not see anything from AMD or Intel that makes this CPU have a rival that will lower it from the pedestal as the best processor of games in a long time.
