Applications

Asus Nvidia GeForce GTX 650 Ti, a PCI Express 3.0 ×16 graphics card

PCI Express operates in consumer, server, and industrial applications, as a motherboard-level interconnect (to link motherboard-mounted peripherals), a passive backplane interconnect and as an expansion card interface for add-in boards.

In virtually all modern (as of 2012) PCs, from consumer laptops and desktops to enterprise data servers, the PCIe bus serves as the primary motherboard-level interconnect, connecting the host system-processor with both integrated-peripherals (surface-mounted ICs) and add-on peripherals (expansion cards). In most of these systems, the PCIe bus co-exists with one or more legacy PCI buses, for backward compatibility with the large body of legacy PCI peripherals.

As of 2013 PCI Express has replaced AGP as the default interface for graphics cards on new systems. Almost all models of graphics cards released since 2010 by AMD (ATI) and Nvidia use PCI Express. Nvidia uses the high-bandwidth data transfer of PCIe for its Scalable Link Interface (SLI) technology, which allows multiple graphics cards of the same chipset and model number to run in tandem, allowing increased performance. AMD has also developed a multi-GPU system based on PCIe called CrossFire. AMD and Nvidia have released motherboard chipsets that support as many as four PCIe ×16 slots, allowing tri-GPU and quad-GPU card configurations.
