Elmer,

The P4 posted the highest integer scores ever measured for any processor on the planet in SPEC2000 and by a significant margin. Those scores were measured running WIN2000 and now you claim it won't benefit from code optimization because it stinks at integer???

That may be so, but it has a lot of trouble with Excel. Unfortunately (for Intel), the ratio of Excel users vs. SPEC Int users is about million to 1. (Intel compiler team being the only users).

I don't know about the code that's in SPEC int, but it is apparent that P4 just chokes on a common application code with a high frequency of hard to predict branches. No amount of SSE2 optimization is going to help here. Only a 30% or higher lead in the clock speed is going to keep P4 competitive.

Joe this is a silly argument. The P3 tops out at a little over 1GHz on the .18u process and P4 will hit 2GHz on the same process.

The 2 GHz remains to be seen, but what matters is where Athlon will be on the .18u process. Intel needs to be 30% higher.

If all you cared about is frequency for marketing purposes then P4 is still far and away the leader regardless of it's lead in pure performance.

Agreed. MHz sells. That's what P4 is all about.

Joe

Elmer,

It is good to see that Intel has done such good work on their SPEC compilers, and that the P4 runs SPEC so fast.

Those of us who sit at their desk running SPEC all day long, will be thrilled.
