PCI-SIG, the organization that controls the official specifications of the standards of this well-known port, today released the final specifications of the new PCIe 4.0 standard. The new rule doubles the speed of each PCIe line. So you will need fewer lines to power devices connected to this port. Or those who need the 16 tracks will see how the bandwidth is doubled allowing to move too much more powerful devices.
PCI-SIG publishes the final specification of the PCIe 4.0 standard
“We have seen an unprecedented early adoption! Before its publication, we have confirmed the existence of numerous providers with 16GT/s silicon PHY and IP providers that already offer a 16GT / s controller. Given the interest, we conducted a Pre-Release Compliance Workshop with preliminary FYI testing only for the PCIe 4.0 architecture that attracted dozens of solutions. We will continue to test FYI in our workshops for the rest of the year. ”
As they announce, many vendors have already prepared themselves in a preventive way to the arrival of the new standard including controllers. That will support these speeds even before their launch in their designs. So with the appearance of the new rule, we should start to see plates based on 2018 PCIe 4.0 during next year, along with a whole legion of modern GPUs, NVMe SSDs, and other compatible devices.
PCI-SIG also announces its plans for the arrival of PCIe 5.0 for the second quarter of 2019. Also, for which it plans merely to double the speed of lines again concerning PCIe 4.0. A notable change that implies that in 2020 four PCIe 5.0 lines will offer the same bandwidth as sixteen PCIe 3.0 lines.
All these changes come due to the needs of SSDs and graphics cards in the future. Since with the arrival of formats as hungry of bandwidth. As it can be the video to 8K or 16K you need this type of changes to be able to supply new graphics cards with enough bandwidth or shapes. So that new NVD SSDs can still be much faster than the current ones.
