Definition Definition
Each PCIe version corresponds to a specific data transfer rate between
the processor and peripheral devices. Generally, a version update
corresponds to an increase in transfer rate.
The PCIe technology is under constant development. For the latest
information, see the PCI-SIG website
PCIe devices communicate through a logical connection called an
interconnect or link. At the physical level, a link is composed of one or
more lanes. The number of lanes is written with an x prefix with x16
being the largest size in common use.
These numbers correspond to the maximum link bandwidth supported by
the slot.
