PCI Express 3.0: The Timeline

PCI Express 3.0: On Motherboards By This Time Next Year?
By

Al Yanes, president and chairman of PCI-SIG, and Ramin Neshati, chairman of the PCI-SIG Serial Communications Workgroup, addressed the current timeline of PCI Express 3.0 development.

On Wednesday, June 23rd, PCI Express 3.0 revision 0.71 was released. Yanes stated that the 0.71 release marks what is believed to be the resolution of the backward compatibility issues that had caused an initial delay. Neshati described the primary compatibility issue as “DC wandering,” which he explained as PCI Express 2.0 and earlier devices “not having enough zeros and ones” to satisfy the demands of the PCI Express 3.0 interface.

Now that the backward compatibility issues are resolved, the PCI-SIG says it is on track for the base release of the 0.9 revision “later this summer.” This is expected to be followed by the base release of revision 1.0 in the fourth quarter of this year. 

Of course, the most pressing question is when can we can expect to see PCI Express 3.0-based motherboards on store shelves. Neshati stated that he expects to see initial products in the first quarter of 2011 (the “FYI” triangle on the Timeline image). 

Neshati added that there would be “no silicon-impacting changes” (the only changes would be software/firmware-related) between revision 0.9 and revision 1.0, which is what will allow some products to start to trickle into the marketplace before the final release of the 1.0 revision. During this time, products will be able to qualify for the PCI-SIG “Integrator’s List” (the “IL” triangle), which is PCI-SIG’s version of an approval logo.

Neshati jokingly referred to the third quarter of 2011 as the “Fry’s and Buy” date (an apparent reference to Frys.com and either Buy.com or Best Buy). This is the time in which we can expect to see a large selection of PCI Express 3.0-based merchandise for sale on the Web and in retail stores.

    Good article with some nice teases. Seems us regular users of high end machines won't see a worth until 2012. Just in time for my next build!

    Good news to peoples like me who haven't spent any money on PCIE 2.0 DX11 card due to nVidia's delay in shipping GTX460.

    Can't wait to see PCIE 3.0, native USB3/SATA3, DDR4, quad channel and faster&cheaper SSD next year.

    In addition, I hate unreasonably priced buggy HDMI and would also like to see the Ethernet cable(cheap, fast and exceptional) based monitors as soon as possible.

    One more tech that I can't wait to see: http://www.tomshardware.com/news/silicon-photonics-laser-light-beams,10961.html

    WOW, so much new techs to be expected next year!

    I havent read this entire article but on a related note I was told that within the Sandy Bridge family, at least on the server side, the higher end products will get PCIe 3.0.

    And if you think the Core i3/5/7 desktop naming is confusing now, wait till Intel starts releasing all their Sandy Bridge Server chips. Its going to be even worse I think.

    And while we're talking about futures, 32GB DIMMs will be out for the server market most likely before the end of this year. If 3D Stacking and Load Reducing DIMMs remain on track, we could see 128GB on a single DIMM around 2013, which is when DDR4 is slated to come out as well.

    After an unfortunate series of untimely delays, the folks behind PCI Express 3.0 believe they've worked out the kinks that have kept next-generation connectivity from achieving backwards compatibility with PCIe 2.0. We take a look at the tech to come.


    It's nice to see the backwards compatibility and cost be key factors in the decision making. Especially considering that devices won't be able to saturate it for many years to come.

    Nothing in the world of graphics is getting smaller. Displays are getting larger, high definition is replacing standard definition, the textures used in games are becoming even more detailed and intricate.

    Even the graphics cards are getting bigger! :lol:

    We do not feel that the need exists today for the latest and greatest graphics cards to sport 16-lane PCI Express 3.0 interfaces.
    Glad you said today, since when Crysis 3 comes along its all back to the drawing board, again.

    Still, the largest cards today are a bit too large! Aren't they!

    A series of unfortunate events? That sounds familiar...

    Very pleased with all this, looks like 2012 Q1/2 will be my new PC build, should all come together nicely then!

    This article could have been written in a sentence. PCI-E 3.0 will be out in 2011 and will be faster.

    Perhaps you could have explained why CUDA would benefit from this, or what type of apps that use it could. Fusion makes no sense to me, since the GPU and CPU will not be connected using PCI-Express, and be on the same die. Maybe you could explain why these things are going to benefit.

    Also, according to the visual, latency will be lowered. Bandwidth is essentially irrelevant in many situations, since it's only rarely fully used, but latency could make itself felt in virtually anything.

    You also could have included the extra power use this extra speed will take. It almost certainly will, all other things being equal. That's a huge consideration. If I have to add, say 15 watts to my motherboard, is it worth it for a technology that might not be relevant for many situations, in the relative near term? If it's one or two watts, it's a no brainer, but, if it's a lot higher (which I suspect it might be), people need to really ask if they need this technology, or if it's better to wait until the next purchase, when it might have more value.

    they should integrate Intel's new optic technology in to it give it twice the bandwidth on top of that 64 gb/s or more
