– Step by step -- Evolution of PCI Express

Evolution of PCI Express

  • PCI Express (Peripheral Component Interconnect Express) is a communication interface that allows the connection of peripheral devices to a motherboard of computer.
  • It was developed by Intel in 2004 as an improvement to the previous PCI (Peripheral Component Interconnect) standard.
  • The first version of PCI Express It featured a data transfer speed of up to 2.5 gigabits per second (Gbps) for each connection lane.
  • With the advancement of technology, new versions of PCI Express were launched with greater bandwidth and transfer speed.
  • The second version of PCI Express It was introduced in 2007, doubling the transfer speed per lane to 5 Gbps.
  • The third version of PCI Express, launched in 2010, increased transfer speeds to 8 Gbps per lane.
  • In 2017, the fourth version of PCI Express was presented, which reaches a transfer speed of up to 16 Gbps per lane.
  • In addition to the transfer speed, PCI Express has been evolving in terms of bandwidth, allowing the connection of more high-speed devices simultaneously.
  • PCI Express has revolutionized the computing industry, providing greater connection capacity and improving performance of the devices peripherals.
  • Today, PCI Express is widely used in different areas., such as graphics cards, sound cards, hard drives, among others.
