Re: Did you note that AMD used Intel's C/C++ Version 4.0 Compiler for these tests ?

Yes, and they post SPEC results for both Coppermine and Athlon on their site with both chips using that same compiler - and Athlon is faster. Intel has developed some great SPEC optimizations that they are showcasing with Coppermine.

What limits would you guess have been put on the use of that optimized code by Compaq, for instance?

I'm not complaining, it's a perfectly legitimate thing to do, and my hat's off to the assembler guys who tweaked the code.

But those giant SPEC scores are probably not very good indicators of performance relative to other chips.

Performance on actual applications, some of which Coppermine is very good at, but most of which Athlon leads by a bit, are the indicators that are most meaningful for users of actual applications.

As has been said before, clock for clock, the performance of the two chips is similar enough right now that this is a megahertz race.
