PCIe 4.0 Will Arrive in 2017

Al Yanes, president and chairman of the PCI-SIG, told PCMag that version 4.0 of the PCIe specification will be out early next year. According to this article, PCIe 5.0 is already on PCI-SIG's future roadmap. PCIe 4.0 will essentially double the interconnect performance bandwidth of the current 3.0 specification, from 8 gigatransfers per second (GTps) to 16GTps. In addition, it introduces new technologies to enhance power efficiency: the use of an L1 substate that drastically lowers power use in idle mode; half-swing and quarter-swing, which cut power consumption by 400mV and 200mV, respectively; and high-speed data transfer bursts with minimum idle power.
