Next-gen NVIDIA GeForce GTX 280, GTX 260 Specifications Unveiled

    NVIDIA's upcoming Summer 2008 lineup gets some additional details

    Later this week NVIDIA will enact an embargo on its upcoming next-
    generation graphics core, codenamed D10U. The processor will make its
    debut as two separate graphics cards, currently named GeForce GTX 280
    (D10U-30) and GeForce GTX 260 (D10U-20).

    The GTX 280 sports all of the features of the D10U processor, the GTX
    260 version will consist of a significantly cut-down version of the
    same GPU. The GTX 280 version of the processor will enable all 240
    unified stream processors. NVIDIA documentation, verified by
    DailyTech, claims these second-generation unified shaders perform 50
    percent better than the shaders found on the D9 cards released earlier
    this year.

    The main difference between the two new GeForce GTX variants revolves
    around the number of shaders and memory bus width. NVIDIA disables 48
    stream processors on the GTX 260 version. GTX 280 ships with a 512-bit
    memory bus capable of supporting 1GB GDDR3 memory; the GTX 260
    alternative has a 448-bit bus with support for 896MB.

    GTX 280 and 260 add virtually all of the same features as GeForce
    9800GTX: PCIe 2.0, OpenGL 2.1, SLI and PureVideoHD. The company also
    claims both cards will support two SLI-risers for 3-way SLI support.

    Unlike the upcoming AMD Radeon 4000 series, currently scheduled to
    launch in early June, the D10U chipset does not support DirectX
    extentions above 10.0. Next-generation Radeon will also ship with
    GDDR4 while the June GeForce refresh is confined to just GDDR3.
    The GTX series is NVIDIA's first attempt at incorporating the PhysX
    stream engine into the D10U shader engine. The press decks currently
    do not shed a lot of information on this support, and the company will
    likely not elaborate on this before the June 18 launch date.

    After NVIDIA purchased PhysX developer AGEIA in February 2008, the
    company announced all CUDA-enabled processors would support PhysX.
    NVIDIA has not delivered on this promise yet, though D10U will support
    CUDA, and therefore PhysX, right out of the gate.

    NVIDIA's documentation does not list an estimated street price for the
    new cards.

  2. I am not giving up my HD3870 card anytime soon for a newer card. At
    least for a couple of years.
