The performance of Nvidia’s Ampere-based RTX 30 series cards may be reduced due to CPU bottlenecks
Under normal circumstances, the higher the performance of the hardware combination, the better the overall performance. If the performance of single hardware is relatively high, the performance of the hardware combination cannot be improved.
For example, when you use a high-performance graphics card with an older processor with lower performance, the overall performance of the graphics card may be dragged down by the old processor.
Although this situation does not happen 100%, it is now found that the performance of Nvidia’s Ampere-based RTX 30 series cards will be reduced due to the bottleneck of CPU performance.
The media recently tested Guerilla Games’ Horizon Zero Dawn, Ubisoft’s Watch Dogs: Legion, Square Enix’s Shadow of the Tomb Raider, and more. These large games will consume a lot of processor resources.
At the same time, these games are built based on DirectX 12 API. During the test, the media set the image quality to low quality and medium resolution to ensure that it will not affect the graphics card.
The Hardware Unboxed uses AMD and NVIDIA graphics cards and AMD and Intel processors to combine to observe the impact of low-performance processors on graphics performance.
In the case of the same frame rate, NVIDIA graphics cards seem to need to use more processor resources for rendering, so the requirements for processor performance are relatively higher.
Although AMD graphics cards will be affected when paired with low-performance processors, overall AMD graphics performance is better than RTX 30 series graphics cards.
From the test results of these games, it can be seen that NVIDIA’s new graphics cards are significantly affected by the processor’s performance. In this regard, NVIDIA’s performance is not as good as AMD’s graphics cards.
Therefore, if gamers need to play certain large-scale games, especially those that take up more processor resources, it is not enough to just improve the performance of the graphics card.
Because the weaker processor performance will directly drag down the performance of the graphics card and lead to a decline in the gaming experience, for example, most entry-level processors in the test have this situation.
