PCI Express cards
PCI Express improves system attributes and enables a low-power, scalable, high-bandwidth
communication path using a small number of connections, or wires, compared to traditional parallel
interfaces such as PCI. The PCI Express I/O slots can support other PCI Express cards with less bus
bandwidth than what is physically defined for the slot. Use the following table to determine PCI Express
card compatibility.
