A full-length slot may carry sixteen lanes, eight lanes, four lanes, or even one lane depending on the motherboard design and current resource allocation.</p> <p>PCIe calls these arrangements link widths. Common widths include x1, x4, x8, and x16. The number after the x indicates how many lanes participate in the link.</p> <p>That distinction matters for graphics cards, storage adapters, network cards, capture hardware, accelerators, and other devices that can move large amounts of data through an expansion slot.</p>
