He claims the Prescott's 64-bit extensions are different, and Intel won't implement it in this chip, but rather wait until the Tejas *T recension, which is supposed to arrive next year.Source: The Inquirer
Current roadmaps Intel is showing its partners demonstrate that Prescotts will clock to 4GHz by the end of the year, with the firm talking vaguely about a "next generation" chip. Intel's problem is that it find itself in the horns of a dilemma. If it does pre-announce a 64-bit extension desktop processor, it may have a difficult job explaining just how such a chip fits in with its current Itanium 64-bit processor.
But Intel has had difficulty explaining things before when it changes its mind – with the Rambus affair being the biggest volte face in recent times.
