    I just thought of something. The difference between 32 and 64 bit
    processing has other differences than pipeline alone. You realize
    that the 64 bit processors could theoretically utilize up to 16
    terrabytes of RAM. It is a well know n fact that even 16 bit apps
    have ahard time when being run in a system with 32 bit amounts of RAM.

    How will AMD cover up the 20 GB of RAM while doing something backwards
    compatible?
