SATA III, USB 3.0, PCIe 3.0

I want my next motherboard to have SATA III, USB 3.0 and PCIe 3.0
Does anyone know when Intel will have a chipset that supports all 3?
I'm trying to plan out what type of upgrades to buy while I wait for the next big rev of motherboard standards.

  1. it will be a long time pcie 3 has been delayed until Q2 2010
  2. Yes, I've read about PCIe being delayed.
    Maybe I could restate my question. When and what will be the Intel X58 chipset replacement and will it support SATA III, USB 3.0 and/or PCIe 3.0? I'm not hung-up on Intel, I'm just trying to get a feel for 2010. From what I have Googled, it looks like perhaps no major technology upgrades will happen to motherboards in 2010. Will 2010 be little different from 2009 motherboard wise?
  3. ASUS has a work-around for SATA/6G on their latest P55 motherboards;
    scroll down to the block diagrams here:

    Note, however, that there is still a theoretical bottleneck
    at PCIe x1 Gen 2, which supports only 500MB/second
    in each direction, whereas SATA/6G @ 10 bits per byte
    supports 600 MB/second.

    So, this workaround is not ideal, but it should make
    a difference for the first crop of SSDs that will have
    a 6G interface.

    Seagate also have a Savvio 2.5" HDD model 15K.2 with SAS/6G support:
    but this is a 15,000 rpm rotating platter with a practical data rate
    hovering around 150-160MB/second, directly under the read/write heads,
    which is just now saturating SATA-I (150MB/second). reports that ASUS is also developing
    an add-on controller that supports SATA/6G,
    using the same chips -- with probably the same
    theoretical bottleneck of 500MB/second (as above):

    See also Intel's RAID controllers model RS2BL080
    and RS2BL040 ("Big Laurel 8" and "Big Laurel 4"
    respectively): these are enterprise-class SAS/6G
    add-on controllers available now from Intel and
    from LSI under the MegaRAID brand name:,2392.html

    Based on the published specs, these Intel RAID controllers
    should work at max bandwidth in all existing x8 PCI-E 2.0 slots.

  4. I stumbled on this while looking for something else. But just to clarify, SATA III and USB 3 are available now, it appears vendors are implementing it by using some of the available PCIe 2.0 lanes.

    ASUS' add on card uses an x4 slot, not the x1 that was proposed in the article above. It supports two SATA III and two USB 3 ports. It would require complete saturation of all 4 ports to saturate the x4 card, which seems somewhat unlikely ATM (IIRC, there's only 1 drive available that can even saturate a SATA II connection).

    I am hung up (in a good way) on Intel, and I'm very much looking forward to seeing the Intel chipset that will support USB 3, SATA III, and PCIe 3. Does anyone know if Intel has released any preliminary specs?
