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.

    only thing that i would like to know is the pricing, since its on par performance wise with the other entusiast boards, the one thing that will seperate itself will be pricing.

    WTF, these aren't bartons! Props to ATi for including something that high. 4.0vdimm is good too.

    The white PCB is....interesting, to say the least. Just going to leave it at that. ;)

    If these are actually out in Mid-October/Nov. I'm def. going to get one.

    I am impressed to say the least. IGP versions will be coming along with Crossfire versions. There are 4 different flavours coming and 8 if you count the addition of IGP. This may lead to a breakthrough into the OEM's. The true test will be how the intel chipset performs.

    Excellent job ATI!

    That white mobo is supa hot. When I saw that pic, my jaw dropped. PRETTY MOBO.

    Too bad I'm an all-Mac shop now. I need a mobo like this in my G4. :-P

    I wanted to buy this mobo when I saw the awesome colours, but the featureset sealed the deal. If this board can overclock like it should, I will buy it without any further question. This has massive potential..

    Just think.... now if they just had a TypeR sticker on it somewhere... :rolleyes:

    is there any mention of the price? Competitive performance at a non competitive price still means little for ATI

    and also the limited availability (ala rs480) might also kill some of this products hopes

    hopefully though they will make a spash and give nvidia a kick in the pants to lower their prices :)

    Nice to finally see a amd64 board with decent quality onboard audio, wonder if anyone will revise their nf4 boards to support the better codcec?

    I guess you missed the MSI with on-board SBlive?
