    Rumors

    * The G80 is expected to be released anywhere from October to November of 2006, although, as of August 2006, with no official word from nVidia, a 2006 launch seems unlikely.
    * It will be the first Direct3D 10 and Shader Model 4.0 card to be released.
    * The G80 will be a 32 pipeline card with 32 pixel shaders, 16 vertex shaders, and 16 geometry shaders per core. The vertex shader pool and geometry shader pool may be unified.
    * There will be 2 cards released at launch, the flagship 8800GTX and the slightly slower 8800GT. The 8800GTX will have 512 MB of ram while the 8800GT will have from 256 MB-512 MB of RAM and will also have slower core and memory clock speeds, and possibly fewer pipelines, than the 8800GTX.
    * The launch price of the 8800GTX will be $499-599 while the 8800GT will initially cost $299-399. [1]
    * Following the introduction of the flagship 8800 range, NVidia will introduce cheaper, slower versions of the card with one or more of the following reductions in capability: (a) reduced core clock speed; (b) reduced memory clock speed; © reduced memory bus width; (d) reduced pipeline count; (e) reduced chip count (if the 8800 is, in fact, a dual chip part); and / or (f) reduced complement of memory. If previous the NVidia naming convention is followed, mid-range products will be identified by model number 8600, and low-end parts will be named 8300.
    * The G80 will not have unified shaders, but will still be DirectX10 compliant.
    * The memory interface is said to be Samsung's new GDDR4 specification.
    * The series is also rumored to have fast memory and core clocks, but will still be built on 90nm technology to avoid unnecessary risks.
    * Anandtech reports that the next generation of GPUs will range in power consumption from 130W to 300W. This increase in power consumption will make for higher-wattage Power Supply Units (in the 800 to 1100 Watt range) and/or the addition of internal, secondary PSUs solely for powering the GPUs. [2]
    * The G80 should also feature UDI connections with full HDMI support.
