, which is responsible for developing the PCI Express spec, has announced some preliminary details about PCIe 4.0.
After technical analysis, the PCI-SIG has determined that 16 GT/s on copper, which will double the bandwidth over the PCIe 3.0 specification, is technically feasible at approximately PCIe 3.0 power levels. The data also confirms that a 16GT/s interconnect can be manufactured in mainstream silicon process technology and can be deployed with existing low-cost materials and infrastructure, while maintaining compatibility with previous generations of PCIe architecture. In addition, the PCI-SIG will investigate advancements in active and idle power optimizations, key issues facing the industry.
The final PCIe 4.0 specifications, including form factor specification updates, are expected to be available sometime in the 2014-2015 timeframe.
