An interesting comparison on Techpowerup makes it clear that it will take quite some time before we can meet graphics cards that are capable of maximizing the bandwidth that is maximized by the new and new communications trunk
Besides improving performance, improving work efficiency and increasing the number of available cores has brought us The Ryzen 3000 generation An interesting line in the form of first-of-its-kind support for the PCI-Express 4.0 standard, whose name even stars on the official packages of the products - along with motherboards In the X570 chipset וRadeon RX 5700 and Radeon RX 5700 XT cards Which are all suited to technology and together are supposed to allow double-bandwidth use from that known to us in the age ofPCI-Express 3.0. Is this really a big news that has dropped the scales in AMD's favor? The answer is yes and no, at the same time.
Members of the Techpowerup site Were quick to conduct a practical examination Of the new device under The Radeon RX 5700 XT card In a variety of modern gaming titles, and came back with conclusions that are not so surprising - even under a basic modern resolution of 1080p (the width of the film consumed by the author of thePCI-Express Mainly affected by the number of processed frames per second, and less than the display resolution of each frame) PCI-Express 4.0 × 16 and artery PCI-Express 3.0 × 16 and even between an artery PCI-Express Veteran 2.0 × 16s are minimal and stand at 3-4 percent in extreme cases, and at less than 2 percent on average.
With any modern resolution you choose - you will not be able to tell the real difference between a maximum bandwidth of the new era and a bandwidth of half or even a quarter of it

While it's great to see the AMD Frustrating to the future and adopting new hardware technologies, this test proves beyond a doubt that it will be a long time before we can meet graphics cards that can express the advantages of thePCI-Express 4.0 - This is when today also a connection PCI-Express 2.0 × 16 (which gives a bandwidth similar to only a quarter of the connectionPCI-Express 4.0 × 16) Enough not to create a bottleneck in systems at any stage and under any conditions.
Buying a motherboard from the X570 family solely in the hope of getting maximum and improved performance from the graphics card in the system is not a wise move, then - however buying an X570 board for the option to use faster NVMe drives is actually a real and practical option here, as we started See Already in the first products based on the Phison E16 controller. But it is doubtful that we will see the storage drives further improve later thanks to thePCI-Express 4.0 so that the standard is not superfluous at all - but as smart consumers you should be aware of where its benefits are reflected and where not really.
