PCI Express 3.0 is barely out the door, but that hasn't stopped the PCI-SIG consortium from unveiling the initial specs for PCI Express 4.0, which promises tons of bandwidth for graphics cards when it's finalized two or three years from now.

Gamers will be most interested in how much bandwidth the new standard will provide their video cards for graphics crunching, and PCIe 4.0 should deliver 16 gigatransfers per second (GT/s), or about double the rate of PCI Express 3.0 (which had already doubled bandwidth of PCIe 2.0). It will also be backwards compatible with previous PCIe generations.

The timing for the announcement is somewhat curious, because PCI Express 3.0 is only becoming a spec worth watching with the launch of Intel's new X79 chipset. Of course, there isn't an ecosystem that even supports PCIe 3.0 yet, so you might be waiting up to 5 years for some PCIe 4.0 goodness. Who knows what the computing landscape will look like by then?

    nice, honestly im still using ver.2 didnt even know they had a 3 much less a 4 coming lmao, wow im in the past need to do more research and less work lmao. ver.2 is fast enough for me using 3 cards but wow couldnt imagine running four cards on a ver.4 wow, add 4 gigs of card mem. and im set lmao.

  • What will be the effect on Thunderbolt?

    Since Thunderbolt is designed to extend the PCIe bus outside the computer, does anyone know if is there any effort to ensure Thunderbolt will be capable of PCIe-4 speeds? (Thunderbolt II, a.k.a. Warthog, anyone?)

      @JJMach I don't know, but PCI-SIG is working on their own technology to extend PCIe outside the computer.

    should be nice. we just have to wait to 21 des 2012 of armageddon. we will never (w) see 2013. (black cat black dog) cought.. hope to get pcie 3.0 innstalled first. but for heavy rendering like dx 11.1 dx12 13 14... and so on we need raw power.pcie 4.0 12 w +12 w x-fire sli support 11.5 w and 10.9 w. thunderbolt 2 yes but still i cost wery little to get a x4 x4 mini pcie with TB in a desktop computer. new tec every year. oh i enjoy to be a costumer. but shurly it cost to be big. ?????? $$$ .
