wbmw, it's not that difficult to understand...

Intel obviously had trouble with 90nm besides P4 design because Dothan was delayed about as much as Prescott, because leakage was higher even in a low voltage design then they had anticipated. Intel would not have delayed if they hadn't faced an issue with Dothan. From what I heard it was exactly the same issue (leakage) that delayed both. From another angle: Intel would never have created Prescott if they'd known about higher than expected leakage beforehand. Íntel's 90nm problems were magnified for all to see with Prescott, but they applied to their other products too (same process with higher than expected leakage) but in a lesser manner because voltage and frequencies (and hence leakage) are less than with Prescott. Same problems, but in a less excessive manner.

FWIW, AMD had the same problems too but again in a lesser manner because of lower frequency, and SOI (that doesn't solve the main leakage problem but does give some more breathing room by reducing total leakage).

Hope this explains to you what I meant.
