PCI-Express 4.0 to arrive next year, first PCIe 4.0 devices are being shown off at IDF 2016

The PCIe 3.0 was released back in 2010, and it’s about to move forward with PCIe 4.0. Although the new generation of PCIe still not officially launched yet, a PCIe 4.0 devices are being shown off at the Intel Developer Conference, IDF 2016, showcasing a demand for increased PCIe bandwidth for future products for both high-speed networking and storage solutions.

The upcoming PCIe 4.0 will offer 2x the bandwidth of existing PCIe 3.0, giving 16GT/s rather than 8GT/s. This allows x8 PCIe 4.0 devices to provide the same bandwidth as PCIe 3.0.

This added bandwidth would allow PCIe storage devices get much faster and allow future multi-GPUs to communicate more easily through the PCIe bus, potentially taking away the need for external bridge connections for Nvidia’s SLI multi-GPU solution.
roadmaps from Intel which show when PCIe 4.0

As you can see the roadmaps from Intel which show when PCIe 4.0 will be added to consumer or enterprise motherboards, but it will essentially allow Intel products to get a lot more bandwidth out of their PCIe lanes. This will allow future servers to use increasingly high bandwidth networking and storage solutions.
