The numbers don't match the P4 exactely but that's not the point
the point is that the Athlon's are still good overclockers just as good as, if not better than, any P4 out now
you don't hafta crank an Athlon up 1ghz to make it perform like the P4's
the 83:100 ratio is close
of course if you don't agree with it then change it a bit or better yet benchmark
you'll see that the athlon's top-end overclock is now easily up there with the P4's top-end overclock
they have really gotten their .13 process in line
