!!! Overview
[{$pagename}] (Peripheral Component Interconnect Express), officially abbreviated as [PCIe] or PCI-e, is a high-speed serial computer expansion [bus] standard, designed to replace the older [PCI], [PCI-X] and [AGP] bus standards.
[{$pagename}] is the common motherboard interface for personal computers' graphics cards, [hard drives|Disk], [SSDs], Wi-Fi and [Ethernet] hardware connections.
[{$pagename}] has numerous improvements over the older standards, including higher maximum system bus throughput, lower I/O pin count and smaller physical footprint, better performance scaling for bus devices, a more detailed error detection and reporting mechanism (Advanced Error Reporting, AER), and native hot-swap functionality. More recent revisions of the PCIe standard provide hardware support for I/O virtualization.
[{$pagename}] is defined by its number of lanes, the electrical interface is also used in a variety of other standards, most notably the laptop expansion card interface ExpressCard and computer storage interfaces [SATA] Express, U.2 (SFF-8639) and M.2.
[{$pagename}] format [specifications] are maintained and developed by the PCI-SIG (PCI Special Interest Group), a group of more than 900 companies that also maintain the conventional PCI specifications.
[{$pagename}] is part of the [Thunderbolt] 3.x [specification] which combines [{$pagename}] with [USB] 3.1 and uses the [USB Type-C] form factor.
