    Have a look at http://www.amd.com/html/products/pcd/mpf/pres1.html and
    follow the arrows. The main features are:

    Cache are 32kB each (I and D), but only 2-way set associative.
    Instruction fetcher performs predecoding and stores the additional
    information along with the instructions in I-cache.

    Floating point multiply takes only 2 cycles (5 on PPro).

    Floating point add takes 2 cycles (3 on PPro).

    Much lower branch misprediction penalty than PPro.

    Fits into a Pentium socket.

    But I don't have any to check their claims. Anyway it looks good even after
    removing marketing hype.
