I've read these rumors too. But you tell me. If Prescott emerges before P4 even reaches 4.0 GHz, what are the chances that P4 will even hit 6.0 GHz? Keep historical precedence in mind.

I'm not sure "historical" precedent really has as much meaning now as it did 5 years ago. The P3 had only been released at speeds of 1GHz when the P4 appeared... The P3 is now at 1.2GHz moving up perhaps as high as 1.4 to 1.5GHz for some applications before being retired.

There are, quite frankly, too many variables here:

Assuming Prescott exists and is actually an x86-32 chip:

1) When will it be ready for production??? Beginning of the 0.09 micron ramp? Middle of the 0.09 micron ramp? Beginning of the 0.065 micron ramp? An early release would tend to limit the life-span of the P4 all other things being equal, but...

2) What is the size of the chip? If it's a large processor, then the P4 may hang around for a generation. The P4 should hit at least 3.0GHz (maybe more) on 0.13 micron. Die size on 0.09 micron should be very favorable, and speeds would probably approach that 4.0GHz number out of the gate... If the new CPU is, however, "of reasonable size," then Intel might push to move as many starts over to the new product as possible. Intel will have 300mm in full swing by this point...
