Is the NVIDIA RTX 3090 losing performance on PCIe 3.0 motherboards



Is the NVIDIA RTX 3090 losing performance on PCIe 3.0 motherboards

The latest generation graphics cards are already compatible with file type 4.0 PCI-Express interfaz, a visual interface that doubles the PCI-Express 3.0 bandwidth and raises reasonable doubts as to whether it will be necessary to make the most of NVIDIA's new flagship.

With the green power supply of the RTX 3090, there are many users who have ever wondered if having a platform with PCI-Express 3.0 would be problematic or otherwise they would be able to get all the functionality of the new graphics that they can provide you with. Fortunately, a representative from NVIDIA came forward to resolve this question.

Is PCIe 3.0 enough to get the most out of the RTX 3090?

“System performance is affected by many factors, and the impact varies depending on the application. This effect is only a small percentage when mov ing from PCIe 4.0 x16 to PCIe 3.0 x16, and in fact the processor selection will have a greater impact on performance than using the PCI-Express interface. We look forward to new platforms that can take full advantage of Gen4's power to maximize potential performance. “

What the NVIDIA representative confirms with these statements is that the successful use of the PCI-Express 3.0 x16 interface with the RTX 3090 will affect its performance, even though it is undermining the importance of losing a small percentage of performance. and that it will be more important to have a more powerful and graphic processor than this.

At that point, we saw a comparison of PCIe 3.0 vs PCIe 4.0 in games, which led to the file VRAM

the picture card was very important in this; games do a lot RAMHidden due to the inability to find enough space in graphics RAM, loading a large amount of texture data into system RAM.

However, as this NVIDIA RTX 3090 incorporates less of less 24GB GDDR6X memory With a 384-bit bus, it seems unlikely that any game will find itself in a situation where it doesn't have enough VRAM to maintain its structure and that it needs to download RAMCaché, so it seems that, at least from a point of view, the NVIDIA Representative is quite right in its claims.

The key to this is yes, you will have a small bottle if you use the GeForce RTX 3090 with PCI-Express 3.0 x16 platform, but the impact will be much lower compared to the bottleneck and performance loss you will experience when using the processor it is not strong enough.

What processor will you need to avoid the bottleneck?

NVIDIA has not commented on this feature, so we can only recommend “high” processors. According to NVIDIA itself and in theory, the more powerful the processor is, the less likely it is to cause a bottle with a powerful RTX 3090, so what we can recommend (and this is just our recommendation) would be the following:

  • Intel Core i7-10700K o higher.
  • AMD Ryzen 5 3600X higher.
