Dear Elmer:

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. In fact, it performs no better than an Athlon at 80% of its clock rate. The only time it goes faster is when it is executing code that is SSE or SSE2 optimized only but, not 3DNow or dual pipe FPU optimized. That violates your recompiled for argument. 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, yet you conveniently deny Athlon hand tuned assembly routines when P4 currently requires them as well. So all we have is current benchmarks and those hand coded for P4.

The current champion CPU in Primordia, QMC, Moldyn, and Linpack is an Alpha. 2nd is an Athlon. P4 is below those and sometimes not even in third. These are real world benchmarks.

And you forgot the list where P4 performs so bad, that it is near the bottom of currently available CPUs.

Rc5
Expendable (640x480)
Sysmark 2000
SPECviewperf 6.1.2 awadvs-04
3D Studio Max 2
Linux Kernel Compilation
IEEE high quality iDCT MPEG-4 encoding

And this list is growing faster than the other one.
