Initially, it was promised that versions of PCIe 6.0 would be available as early as 2021, but there were screw bandwidth constraints. The speed doubled again, from 1.969 GB/s (PCIe x1) to 3.938 GB/s. It took only 2 years for version PCIe 5.0 to be released. PCI Express 5.0Īs technology evolved, it took less and less time to create new versions. Now PCI Express x1 has 1.969 GB/s of throughput, but uses the same line as 3.0 – 128b/130b. PCI Express 4.0Ĥ years ago, in 2017, PCSI-SIG released PCIe 4.0 version. In addition, it had an upgraded line – 128b/130b, which was a lot bigger than in the previous versions. For example, PCI Express x1 2.0 version had 0.500 GB/s of throughput and version 3.0 had 0.985 GB/s. As expected, the speed was improved by almost double. In 2010, PCI-SIG released PCIe 3.0 version. For example, PCI Express x1 version had 0.250 GB/s of throughput and version 2.0 had 0.500 GB/s.

It worked in the same line of code (8b / 10b), but was twice as fast as version 1.0. PCI Express 2.0Ĥ years later, in 2007 PCI-SIG released PCIe 2.0 version.
The first generation was slow compared to the current one, but that was a strong start. In 2003 PCIe 1.0 was launched in the market. It should be mentioned that the PCI Express 1.0 card would work without any problems even on PCI Express 5.0. Recommended to Read: Gaming Keyboards vs Normal Keyboards PCI Express Generations The newer generations offer much better performance compared to the older ones. Moreover, you will find PCIe slots for different generations.
The PCIe X1 is the smallest PCIe slot among all others.
