Making the Most of PCIe Low Power FeaturesPCI-SIG Blog - Scott Knowlton, Marketing Work Group Co-chair, PCI-SIGAug. 27, 2018 |
PCI Express® – also known as PCIe – used to get a bad rap for being power hungry on servers and PCs. But I’m happy to say that this is no longer the case. Are you aware that PCIe today is extremely power efficient with built-in low power features? By delivering an I/O technology that delivers high performance, low cost AND low power, PCI-SIG has ensured that PCIe is the interconnect of choice – across multiple devices, including smartphones, tablets, IoT, laptops, and more. On a mobile phone for instance, low power is a stringent requirement, and running PCIe delivers the best of both worlds – a high performance solution with low power options.
Let’s take a closer look at how PCIe supports low power devices and applications.
PCI-SIG continually evolves the PCIe specification to improve performance, increase efficiency, and lower power consumption to satisfy the very divergent needs of many different applications. Since the PCIe 3.0 spec, PCI-SIG has focused on reducing power consumption while the PCIe interface is active to enable better platform power management. I’ll give you a quick overview of some definitions and how they work.
