__ has the advantage of being faster than AGP while maintaining the flexibility of PCI. __ has no plug compatibility with either AGP or PCI. __ motherboards still tend to have regular PCI slots for backward compatibility, but AGP slots typically are not also included. __ uses a switching component with point-to-point connections to slots, giving each component full use of the corresponding bandwidth and producing more of a startopology versus a bus.__ is a serial technology, striping datapackets across multiple serial paths to achieve higher data rates. __ uses the concept of lanes, which are the switched point-to point signal paths between any two __ components. Each lane that the switch interconnects between any two intercommunicating devices comprises a separate pair of wires for both directions of traffic. Each __ pairing between cards requires a negotiation for the highest mutually supported number of lanes. The single lane or combined collection of lanes that the switch interconnects between devices is referred to as a link. There are seven different link widths supported by __, designated x1, x2, x4, x8, x12, x16, and x32, There are three major versions of __ currently specified: 1.x, 2.x, and 3.0.
