PCIe has the capability to use a reduced number of lanes if one lane has a failure or a performance issue. Notice how one lane has two unidirectional communication channels. Figure 3.32 shows the concepts of PCIe lanes. An x16 slot accepts up to 16 lanes, but fewer lanes can be assigned. The standard supports an x32 slot, but these are rare because of the length. For example, an x1 slot can have only one transfer lane used by the x1 card inserted into the slot x2, x4, x8, and x16 slots are also available. TABLE 3.8 Comparing bus bandwidthĪnother difference between PCI and PCIe is that PCIe slots come in different versions, depending on the maximum number of lanes that can be assigned to the card inserted into the slot. Table 3.8 shows a comparison of the PCI, PCI-X, AGP, and PCIe buses. PCIe is a serial bus, and data is sent one bit at a time. The older PCI standards, including PCI-X, use a parallel bus where data is sent with multiple 1s and 0s simultaneously. Older PCI, PCI-X, and AGP adapters will not work in any type of PCIe slots.
