<P> PCI Express ( 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 . PCIe 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 - plug functionality . More recent revisions of the PCIe standard provide hardware support for I / O virtualization . </P>
