Bad code. If this is compilate, try Intel's latest compiler. It shall give
30-40% performance increase for the Athlon. Numerics could be faster. Each
piece of code with each compiler and each system will produce different
results.

Your metric is highly skewed. Athlons are slightly faster than a P4 for
most applications. Also, they're considerably cheaper, though of course
you will burn more juice if you have more boxes.
And the gain is sub-Moore. It's saturating.
