And yet again, the bandwidth and gigatransfer rate double over the previous generation, allowing data to be transferred at significantly faster speeds. ![]() PCIe 5.0 is the direct successor of the PCIe 4.0 standard. I'm sure you get the drill by now-each new generation doubles the bandwidth of its predecessor or gets close to doubling it. With PCIe 4.0, it increased to 1.97 GB/s and 16 GT/s, doubling from PCIe 3.0's 985 MB/s and 8 GT/s. With the arrival of PCIe 2.0, it was doubled to 500 MB/s and 5 GT/s, respectively. ![]() ![]() The transfer rate of the first version of the standard, PCIe 1.0, was around 250 MB/s over a single lane (x1) and was capable of 2.5 GT/s (gigatransfers). For the most part, the biggest improvement between different generations of PCI Express is always an increase in bandwidth of almost exactly double.
