The ATI Xpress 200 Chipset Family

At the heart all of the new chipsets and boards are Radeon Xpress 200, whether single GPU or Dual GPU, with integrated graphics or with discrete graphics only. You can find more information on Radeon Xpress 200 in ATI Radeon Xpress 200: Performance, PCI Express & DX9 for Athlon 64 . The North Bridge chips do vary between AMD and Intel solutions, but any of the North Bridge chips can be combined with one of several South Bridge chips from both ATI and ULi.

Last fall's introduction of the ATI AMD chipsets featured the SB400 south bridge. The Sapphire and upcoming Radeon Xpress 200 introductions combine the north bridge with the ATI SB450 south bridge, which features High Definition Azalia audio for both AMD and Intel. This is the first chipset to bring High Definition audio to AMD. The SB 450 also supports PCI-e Gigabit LAN, standard SATA 150, and has improved USB burst performance compared to the earlier SB400 chipset. We will see full SATA 2 support and a completely reworked USB controller in the SB600, which will launch in the 4th quarter of this year.

The various ATI Radeon Xpress 200 north bridges can also be combined with ULi south bridges. The current ULi 1573 provides all the features of the ATI SB450 except integrated Gigabit Ethernet. This includes High Definition Azalia audio. Gigabit Ethernet can be added as an external chip and the ULi 1573 also supports NCQ hard drives, which are not supported on the SB450, according to ATI.

ULi has recently announced the M1675 chipset, which adds SATA II 3Gb/sec SATA to the feature set. The M1573/M1575 family are particularly interesting, since both south bridges are pin-compatible, making the upgrade to M1695 an easy task when the south bridge is finally available to manufacturers.

    This board sounds fantastic!

    Competative with similar Nforce4 boards(DFI LP) isn't enough. They need to beat the price by 5-10 dollars in order to regain the edge. I agree that the VTT options is awesome (for you BH-5 users), but in order to kill the current proven top Overclockers board, they need to be very competative with the DFI in terms of price.

    Also, I was wondering if they managed to fix the cold boot issue with these boards. If the cold boot issue is a non issue with these boards, and they are priced exactly the same as the DFI Lan Party boards, then it is a no brainer for BH-5/CH-5/UTT users as to which board to pick (unless they already are doing the 3.3 Rail Vdimm mod).

    Also, the 2nd page, He art in the first sentence needs to be fixed, and in the first page, it says AMD in the first paragraph when its supposed to say ATI.

    I don't think so, a lot of people complain about problems with the DFI.....and it has a super loud fan on the chipset which is difficult to replace because the video card is right on top of it.

    I personally would never buy a DFI....different people obviously have different priorities

    If this board is rock solid stable like AT reported, then they will have a winner.

    looks like a strong competitor, and here was a typo pg. 11
    "The Sapphire ATI chipset performs at least as fast as the best of nForcee4 chipset boards"
  • Mant - Friday, July 29, 2005 - link

    I think that was intentional. They're comparing the ATI to the "NForcee" by MVidia...like you can compare a Seiko watch to a BOLEX

    In the first pic of the motherboard, it clearly has 8 SATA ports. However, the next page lists the specs with 6 SATA ports and the next picture seems to confirm that. Is there indeed an 8 SATA port version as well?
  • Wesley Fink - Friday, July 29, 2005 - link

    The pictures on page 4 were provided by Sapphire and are earlier prototypes. The actual production version we tested is pictured on page 5 and has 6 (not 8) SATA ports. We apologize for the confusion. There are indeed pads for 8 SATA ports on the production board, so there could be further developments.

    What i like:
    Performance in general
    good audio quality (im wondering if it supports any of the eax extensions though which would be great if it did. Would elimante the need for a sound card.)

    What i don't like:
    bad USB2 performance. This would affect me big time. I have a pro consumer camera (8MP Olympus C-8080) and i usually transfer a bunch of images at a time from my camera to my computer so this is definitly a disapointment.

    I really like nvidia as a company. Their driver team has from the start been top notch. I think that is one of the things that led to their popularity. I generally have always gone with nvidia except in the 9800 pro days because you know why. I currently own a 6600gt which i love. Anyways the only thing that upset me that nvidia did was to take out soundstorm out of thier chipsets. I hope ATI bringing high end audio will force nvidia to reconsider. Nvidia knew that a lot of customers were asking for soundstorm back yet they still wouldn't put it back in. I just don't understand this.

    I hope thier are boards produced that don't have dual video card abilites because of price. I really don't want two video cards. I only occasional play games and im not going to spend 500-900 on two video cards. So we shall see how this plays out.

    The mobo manufacturers were griping about the price. Also, I believe the demand was too low. Yes I know lots of geeks liked it but we're a small percentage of the market.

    "Today, we look more deeply at production version of the ATI Grouper that will be launched by Sapphire next week."
    So, when do we actually see these? If it's by end of Summer, great. If not, it may just be too late. I think most people who've waited for ATI to get this out have already gone to nVidia. I know my buddy has.

    Also, regarding Crossfire, can an AIW X800XT PCIe work with a plain old X800XT PICe?
