The era of PCI-Express 4.0: a greeting to storage, yawning for video cards

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 In an interesting line, the first PCI Express 4.0 support, which even stands on the official packaging 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 of 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 surprising - even under the basic modern resolution of 1080p (the bandwidth required from the author of the - Mainly affected by the number of processed frames per second, and less than the display resolution of each frame) 4.0 × 16 and the artery 3.0 × 16 and even and artery 2.0 × old 16 are minimized and stand at 3-4 percent in extreme cases, and less than 2 percent on average.

In any modern resolution you choose - you will not be able to distinguish a real difference between the maximum bandwidth of the New Age and bandwidth of half or even a quarter of it

While it's great to see the 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 the 4.0 - This is when today is also a connection 2.0 × 16 (which gives only a quarter of the bandwidth of the 4.0 × 16) is sufficient in order not to create a bottleneck in systems at any stage or under any conditions.

Choosing a motherboard based on the X470 chipset or even the B450 can be quite logical and worthwhile for the next generation. 3000 - also without support for PCIe 4.0

Buying a motherboard from the X570 family only in hopes of maximizing performance and improved graphics card processing system is not a wise move, however - but purchasing an X570 board for NVM drives is faster than ever before. Here is a real and practical option, 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 the 4.0 so that the device is not superfluous at all - but as intelligent consumers should be aware of where its benefits come to expression and where not really.

Drives Agile are the biggest earners 4.0 is already today - with much more potential to continue

  1. Excellent article
    To this day I didn't know that there was such a small difference between PCIE2 and 3
    Because at the time I remember actually praising 3
    The fact that the difference between 3 and 4 was not noticeable was much talked about and I was ready for it

    Regarding SSD this is really a blessing to us servers as regular users and I will not feel the difference
    Besides, I don't really get the idea that my SSD has a heat sink that weighs more than the SSD itself (especially on the boards most often have no infrastructure for that)
    Enough I had a mess with video card cooling I had to throw in a new bin for the finish and buy another

    Special thanks to the reporter
    There are not many such great articles on the site

  2. Welcome article that saves a lot of money for those who thought of switching to GEN4 based SSD NVME…

    So even today it is better to buy SSD NVME GEN3… from ADATA SX600 or SAMSUNG 970 EVO PLUS excellent.

  3. Beyond that, ASUS Releases Bios Update Which upgrades panels from the 400 series (X470 + B450) PCI-E 4.0 is free of charge.
    They say there may be limited support or sometimes problems and that you can choose to return to PCI-E 3.0 without restarting BIOS.
