Tom's Hardware Guide has gotten his hands on a few sample of Intel's upcoming CPU's like the Pentium 4 3.6GHz :
The test comparisons show the performance values of the P4 processors that won't officially be available until the middle of 2003. The top model (the 3.6 GHz Pentium 4) will probably make its début in June of next year. At that time, the P4 will be competing against the Claw Hammer-based AMD Athlon 3xxx+. By then, the P4 models with 3.06 GHz and 3.33 GHz will have been introduced. In any case, it has already been decided that the 3.06 GHz version will be available in November of this year. There'll soon be company for the speed monster when AMD introduces the Athlon XP 2800+. More details can be gleaned from the roadmap.
