    i am a newbie to this forum,and i am happy to join with u to learn more
    here i have several questions about the differences between the specifications of ATI and NVIDIA cards.
    1/ frequency. ATI cards run at a much higher frequency,about 100mhz higher than NVIDIA
    2/pipeline. ATI cards have more pipelines builtin, about twice as NVIDIA
    3/memory bandwidth. ATI cards are more likely to corporate a memory bandwidth of 256bit.From 9800pro on, there are various models. While Nvidia has fewer 256-bandwidth cards. eg. the best-seller of nvidia-family:7600gt
    hereby I am puzzled with these differeces. As known,the specifications above are vitally important to tell their performance. But how can these differences results in similar class of performance?

    um currently nvids top end has 24pipes and ati 16. but nvid only has 24 shaders where ati has 48. clockspeed doesnt matter a whole lot in todays world. for the record any x1800/x1900 has a 256bit bus where any x1300/x1600 has 128bit. same for nvid really 8 and 9 series have 256 with 3 and 6 having 128.
