PCI Express (PCIe, PCI-e) is a high-speed serial computer expansionbus standard
PCI Express as a high-bandwidth, low pin count, serial, interconnect technology
It was designed to replace the older PCI and AGPbus standards
PCIe has numerousimprovements over the older standards, including higher maximum system busthroughput, lower I/O pin count and smaller physical footprint, better performancescaling for bus devices, a more detailed error detection and reporting mechanism(Advanced Error Reporting, AER), and native hot-swap functionality
PCI Expressarchitecture provides a high performance I/O infrastructure for Desktop Platforms withtransfer rates starting at 2
5 Giga transfers per second over a x1 PCI Express lanefor Gigabit Ethernet, TV Tuners, Firewire 1394a/bcontrollers, and general p
