Re: "Did you compare the P4 against the Athlon on hand tuned optimized assembly code. I have not seen those benchmarks. I have always said that the SPECmark as currently used is broken. And the P4 does not perform far better than a Athlon given equal optimization"

I gave you data you gave me opinion. As always, you're all mouth no data. P4 uses P4 optimizations and posts the highest Integer scores ever recorded, despite your claim it performs poorly. If you think Athlon scores better then show us the benchmarks where Athlon is optimized vrs P4 optimized. The only ones I know of in existance is SPEC. Athlon SPECFP scores are posted and they do use an Athlon optimized compiler, Compaq Visual Fortran 6.5 Beta. You know what? Athlon still get's it's butt kicked by a slower 1GHz P3. Athlon has never been able to catch even a P3 when running optimized code. That's optimized code vrs optimized code. The only way you can make a case for Athlon performance is to trot out old x87 code with no prefetch, which everyone agrees will look good on an Athlon. Nobody is arguing with you there, we're just saying who cares?

Re: "All currently available compilers (there does not exist one publically yet for SSE2 (IFC 5.0 is not yet available last I looked)) do not have SSE2 optimizations"

Once again you are wrong. The compiler used for the SPEC scores is a commercially available product.

intel.com

I hope you're right about no SSE2 support because that would only extend the P4 lead from it's current 80% advantage over Athlon in FP to who knows how much farther out in front.
