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.
•
PCIe 1.x
•
PCIe 2.x
•
PCIe 3.x
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 "×" prefix with ×16 being the largest
size in common use.
•
×1
•
×2
•
×4
•
×8
•
×16
These numbers correspond to the maximum link
bandwidth supported by the slot.
