PCI Express 3.0 Specs Delayed

By - Source: Tom's Hardware US | B 35 comments

According to PC Magazine, the PCI SIG (special interest group) has decided to officially delay the release of the finalized PCI Express 3.0 specification until Q2 2010. Originally, the specs were due to be released this year, with 3.0-enabled products to hit the shelves in 2010. Now, according to the new date, products compliant with the new specs won't be available until 2011.

The PCI SIG said that the delay stemmed from the need to maintain backward compatibility with products based on current standards, namely PCI Express 1.0 and 2.0. "In this particular case, with pushing the technology so hard, and with PCI gen 3 providing so much more capabilities but with the need to be still backwards-compatible, we had to do the diligence required to move the date," said Al Yanes, president of the PCI SIG.

Yanes added that a big portion of the delay was related to verifying products in the lab, making sure that the older devices can function correctly in the new 3.0 slots. The group is taking extra time to ensure that the three frequencies used by PCI Express--2.5 GHz, 5.0 GHz, and the new 8.0 GHz--can support the new encoding schemes (bumped up from 8-bit and 10-bit to 128-bit and 130-bit) on an electrical level.

Although graphics card manufacturers will be mostly affected by the delay, Yanes said that the member companies of the PCI SIG were satisfied with the group's decision.

    I'd rather have them release it late and well working than have it early and full of compatibility problems.

    everybody is waiting for the 3's. USB 3.0, SATA 3, PCIE 3. and Diablo III.

    Are we maxing out PCIe 2.0? I didnt think Vid cards were.

    PCI-E 3.0 was originally expected for end of this year... now 2011 >_>

    I wanted USB 3.0, SATA III, and PCI-E 3.0 on my next motherboard upgrade but I don't think I can wait for 2 years.

    Actually, it was expected next year. The spec would have been finalized this year, but products wouldn't hit the shelves until 2010.

    :)  I think the real reasons for the delays of PCI-e 3.0, USB 3.0 and SATA III is result of bad economics. The companies are saving money by maximizing the profits from old standards before the new standards are implemented. It is good idea to let the engineers to prefect the spec during the down time of course.

    I agree with haunted one, i'd rather see it delayed and working properly with full backward compatibility then rushed and screwed up.

    It'll be ready when it's ready.

    yep. I can wait, besides, PCIE 16x and 16x 2.0 don't differ all that much anyways. usually just a couple of frames depending on the game. i'd think the same with 3.0

    Yeah... it gets annoying...

    IronRyan21Are we maxing out PCIe 2.0? I didnt think Vid cards were.


    I don't believe we're maxing out PCIe 1.0.
    However, the higher bandwidth is good for crossfire (were you have less lanes meaning less bandwidth, actually hitting a cap).

    PCIe 1 is still good enough for most people. I remember when the 8800GT came out boasting PCIe 2.0 but the reviews said it really needn't because it didn't come close to saturating PCIe 1.0.

    Now with the likes of Radeon 4870x2 and Geforce GTX 295 PCIe must already come in handy. But we can probably wait another year before PCIe reaches it's limit, if it doesn't last even more than that (probably for the mainstream graphics card market it will last another two or three years).

    forgot to add "2.0" at the end of "Geforce GTX 295 PCIe" and before "another year before PCIe". Sorry.

    Big deal. I'll wait contently. :p  If nothing else, it'll give me plenty of time to get more "bang from my buck" from the hardware i already have. It's not like we will see a magical increase across the board with the new spec. It'll take time before the improvements are "realized"

    Just my two cents. :)

    Any one got any links to the actual papers for PCIe 3 fight now? I'm interested in how much power are available for use.

    It's interesting how we want these new 3's. The only new standard, the USB 3 would be used to the full potential here since we have yet even saturated SATA I or PCI Express 1.1 with the current HDDs/GPUs. So the delay shouldn't affect performance at all as you most likely won't gain any performance by going PCIe-3.0 or SATAIII even with the new DX11 cards. I'll gladly wait. PCIe 2.0 and SATAII is working quite well, no bottlenecks to speak of here.

    video cards, probably not, but massive, server raid arrays likely could when the next gen of sata/sas appears (as far as i'm aware, pci-e raid cards are typically 8x and not 16x)

    SATA I has hit peak (with SSDs)and same with PCI Express 1.1 (with GTX 295), just not 2.0.

    While I am in the same boat as you and was looking forward to upgrading on FY-2010, my engineer's background says it is better to wait and hopefully get better hardware than to rush in and get something with design faults.

    Agreed. Oddly, this article reminded me of an ancient PC problem with the i820, ASUS, the P3C2000 mainboard, and the MTH design problem that was rushed into production and later recalled by ASUS, who's customer service back then was worse than terrible.
