"And the P4 will scale a heck of a lot better from 1.5GHz than the P3 will from 1GHz, "

While I will agree with this, that is only because it seems like 1GHz is all that the PIII can do in 0.18 micron. The amount that the P4 can scale beyond 1.5 or 1.6GHz is in some doubt in my mind. Consider the thermal requirements of keeping the Tj at 85 degrees or less. Now currently the P4 is consuming somewhere in the range of 50 watts on the average, but the peak seems to be somewhere in the 70+ watt range. Now there is not enough information to guess what the thermal load at 2GHz would be, but 70 or so average and 100+ watts peak would not be unexpected. Based on this, 1.7GHz may be it until 0.13 micron and/or Northwood. And that is not particularly impressive.
