I'm not sure I understand your question...
I think you want to know the equivalence between pentiums and athlons... I can give you a quick recap of the "C" line of Pentium 4 processors (800Mhz) quite easily:
2.4C - XP2800+
2.6C - XP3000+
2.8C - XP3200+
3.0C - No equivalent from AMD.
3.2C - No equivalent from AMD.
This should be interpreted loosely, of course.
