PCIe 4.0 might launch in 2017


PCI Express has been the standard connector for GPUs for years now. Back in 2011 the latest PCIe version launched: PCIe 3.0. The first GPU that supported it was the HD7970, which launched early 2012. However, a new PCIe revision has appeared. PCI-SIG, the developers of PCIe, hope to finish PCIe 4.0 by 2017, featuring an all new connector as well as a bit speed of 16GT/s (which is double the speed of PCIe 3.0).

Developers hope to have a 0.7 version of the connector finished by the end of this year. When that version is done, only minor tweaks will be made to the technology. PCIe 4.0 will take longer to develop than previous versions of the spec, as PCI-SIG have focused on squeezing in double the amount of copper links that are in PCI 3.0.

In an interview with EE Times, Al Yanes (president of the PCI-SIG), said: “We are getting 16G, something no one thought was possible a few years ago. The base distance is still being validated but it’s typically 7 inches or so. Longer channels of 15 inches or so with two connectors will have retimers, but Gen 3 has used retimers -- now we will need to use them for shorter long channels.”

While PCIe 4.0 will feature a new connector, it will still be backward compatible with GPUs running on PCIe 3.0.

I wonder if they made any improvements at all(if they can) with multi GPUs using the bridge as a Crossfire or SLI connection and were able to get latency down or something along those lines. AMD is the only one using it currently with XDMA but if they are able to get latency down it should help not only with frametimes but VR as well.Quote

Hm, well this is good for servers/ people using pcie to run either crazy volumes of HDD or do seriously beefy number crunching, but most of the market won't see an difference.Quote
