AMD Ryzen 7 3700X Gaming CPU

Our team found that Ryzen’s 3700X has slightly better gaming gains than the Ryzen 7 3800X due to its PBO. Advanced PBO technology allows the processor to match Ryzen 7 3800X in average frame rates across all configurations.

Only 12.6% lower than the AMD Ryzen 7 3700X maximum scores. These results are impressive for an older model and place it at the top of this list.

We found that the 3700X delivers solid gaming performance based on consumer reviews. Its memory controller is the only problem. While it performs better than previous Ryzen models but not better than Ryzen 3800X because of its limited bandwidth, it has high latency and low bandwidth.


  • Requires less power
  • Best for gaming


  • The operating frequency is much lower.
  • Avg. Memory Latency 79.2Pts
  • Avg. Octa-Core Mixed Speed 928Pts
  • Not suitable for heavy uses and streaming.

AMD Ryzen 7 3800X Gaming CPU

The 3800X’s gaming performance is comparable to the i7-9700K benchmarks. The 3800X performs 10% slower when overclocked than the i7-9700K benchmarks but is much faster when used with 64-core processors.

The 3800X is 15% more expensive than any other AMD model. The memory controller in the 3800X is also significantly better than the 3700X and previous Ryzen models.

Another difference is that the AMD 3800X, like all third-generation Ryzen processors, is compatible with the new PCIe4.0-compliant, X570 chipset and with 400- and 300-series motherboards. This is something that you won’t find in the Ryzen3700X.

The AMD 3800X is suitable for heavy tasks such as animation and movie production. AMD 3800X can also be used for HD streaming with dedicated hardware such as NVENC. There will be no dropped frames.

We can conclude that Ryzen 7 3700X is comparable to the 3800X in terms of performance, especially if you’re looking to purchase it for gaming.


  • Higher than others.
  • Use this best for streaming and film production tasks.


  • Additional power required


Ryzen 3800x is suitable for HD streaming?

The AMD Ryzen 7 3800X processor is worth considering if you don’t have the budget or want to stream video. The Ryzen 3800X has an eight-core configuration with 16 threads, making it the perfect choice for streaming.

Are integrated graphics available in Ryzen 7 3700x?

The AMD Ryzen 7 3700x doesn’t come with integrated graphics. Some Ryzen models come with integrated graphics, but not the 3800X.

Do I need a cooler to cool Ryzen 7 3700x processors?

The AMD Ryzen 7 3700X is quiet and does not emit too much heat. This AMD processor comes with a stock cooler which will keep it at the desired operating temperature.

Your usage will also determine the need for a CPU cooler. A stock cooler will suffice for most common purposes. An aftermarket cooler is available if you need more room for overclocking.


The AMD Ryzen 7 3700x and the AMD Ryzen 7 3800x are both excellent processors. It will depend on what your needs are. If you want to use it for applications such as video rendering, then I would go with the AMD Ryzen 7 3800x because it has more cores and threads than the AMD Ryzen 7 3700x.

On the other hand, if you want to use it for things such as editing or compiling, then I would say that the AMD Ryzen 7 3700x would be a better choice.
