The new PCI Express 5.0 standard has now been ratified. This will now allow chip designers to work with the new specifications.

The PCI-SIG worked for 18 months to get the standard ready for ratification. This makes the fifth generation of PCIe available which shows the original intent of scalability has been met easily.

  • Delivers 32 GT/s raw bit rate and up to 128 GB/s via x16 configuration
  • Leverages and adds to the PCIe 4.0 specification and its support for higher speeds via extended tags and credits
  • Implements electrical changes to improve signal integrity and mechanical performance of connectors
  • Includes new backwards compatible CEM connector targeted for add-in cards
  • Maintains backwards compatibility with PCIe 4.0, 3.x, 2.x and 1.x

The faster speed will be widely appreciated mostly with servers which need more bandwidth for database servers etc.

Video cards will jump on the faster speed in principle. Consumer motherboards will be slower to pick up on PCI Express 5.0 primarily as there is already enough bandwidth with PCI Express 3.0 and upcoming PCI Express 4.0 is already overkill.

As PCI Express speeds get faster servers will have issues with risers etc. As the speed increases the distance limitations are problematic. The problem will be worse as speeds rise and there is no real solution to the problem.

For a consumer desktop P,C however, with a standard ATX motherboard. there is no issue with distance from the CPU to the slot.
