Pcie Standard Specification |link|

The first PCIe specification, version 1.0, was released in 2004, with a bandwidth of 2.5 GT/s (gigatransfers per second). Since then, the standard has undergone several revisions, with each new version increasing the bandwidth and improving performance. The current PCIe standard is version 6.0, released in 2021, which offers a staggering bandwidth of 64 GT/s.

If you have ever plugged in a graphics card, an NVMe SSD, or a high-speed network adapter, you have used PCI Express (PCIe). But beneath the familiar slot shapes lies a complex, evolving standard specification that dictates the speed, power, and future of nearly every high-performance computer. pcie standard specification
