mas, Do you have a link for that as I don't remember the word *easy* ever being mentioned.
It was even said on two occasions, once in a CC, once apparently in an interview. Try google as I don´t archive links.
edit: TheInquirer also noted it:
Paul Otellini, Intel's president, went out of his way to say that the firm had absolutely no thermal problems with its 90 nanometre technology, despite speculation.
He said Intel could easily hit the 4GHz envelope with Prescott during 2004.
