The Inquirer has seen some documents from Intel about their upcoming Prescotts for the desktop and mobile market. They write that Intel is still wrestling to reduce the power consumption of their desktop version (103W) and their mobile version (94W). And in future they expect to reduce it even further.
Intel, in the documents we saw, said it is still on track to release Prescott in the fourth quarter of this year. But will it be on 90 nanometers? That's more unlikely, we believe.
Meanwhile, the mobile Prescotts, which are due to launch in Q1 of next year, have different ratings again. There will be two types, one at 74W and the other at 94W. Heatsinks for the mobile Prescotts are rated at 0.45C/W, while the temperature of the 94W baby is 76 degrees Celsius. The following table, scribbled from our notes, is for the desktop processors.
