As a broadly adopted technology standard, PCIe benefits from several decades of innovations with universal support in all major Operating Systems, a robust device discovery and configuration mechanism, and comprehensive power management capabilities that very few, if any, of the other I/O technologies can match. PCIe technology has a flexible, layered protocol that enables innovations to occur at each layer of the architecture independent of the other layers. In this way, power-efficient PHY technologies, such as MIPI M-PHY, can be integrated with the familiar and highly functional PCIe protocol stack to deliver best-in-class and highly scalable I/O performance in tablet and smartphone devices.

As PCs become lighter and thinner and tablets and smartphones become more functional, consumers want seamless, always on/always connected functionality from their computing devices. To respond to these market expectations, device manufacturers need efficient, intelligent I/O technologies. The PCIe architecture satisfies all of these requirements, and with the adaptation to operate over the M-PHY specification it can deliver consistent high performance in power-constrained platforms such as ULT laptops, tablets and smartphones. By delivering this technology, the PCI-SIG is meeting the emerging needs of its members and the industry.
