Re: Machines are getting too damn fast

:How's your P4 for floating point?  Is real-life perf as good as the
:specbench numbers would indicate, or do you need a better compiler

:she runs some really fp intensive workloads.  This Athlon is faster
:than the Serverworks box and (barely) faster than a year-old Alpha
:UP1000 for her code.

    My understanding is that Intel focused on FP performance in the P4,
    and that it is very, very good at it.  I dunno how to test it though.

    GCC generally does not produce very good code, but I would expect that
    it would get reasonably close in regards to FP because Intel's FP 
    instruction set is a good fit with it.
