(Trang mới: '''PCI Express''', officially abbreviated as '''PCIe''' (and sometimes confused with PCI Extended, officially abbreviated as PCI-X), is a computer system bus/[[expansion car...)
As with all computing standards, PCIe is a technology which receives further development and improvement. The current standard version in general use at time of writing is PCIe 1.1 however [[PCI-SIG]] announced the availability of the PCI Express Base 2.0 specification on [[15 January]] []. PCIe 2.0 doubles the PCIe bus standard throughput or [[bandwidth]] from 2.5Gbps to 5Gbps. PCIe 2.0 is still compatible with PCIe 1.1 as a physical interface slot and from within software, so older cards will still be able to work in machines fitted with this new version. Further information on PCIe 2.0 is detailed below.
While in development, PCI Express (PCIe) was referred to as '''Arapaho''' or '''3GIO''' for ''3rd Generation I/O''.
