PCI (Peripheral Component Interconnect) Express is a bus extension standard that appeared in personal computers in 2004. Its purpose is first of all to replace the AGP bus, then the PCI bus on all motherboards. The allocated speeds vary between 312 MB/s and 10 GB/s, compared with 133 MB/s maximum for PCI and 2 GB/s maximum for AGP (Accelerated Graphics Port).
