Intel’s forthcoming “Montecito” member of the Itanium processor family will consume 100 watts, a significant drop from the 130 watts of current models and an advantage in an era when power consumption is a top enemy. The change means Itanium will have about 2.5 times the performance per watt of the current Itanium 2 9M model. The major reason for the lower power is the shift to a new manufacturing process employing 90nm. Intel lowered Montecito’s top speed to 1.6GHz from 1.8GHz and dropped a feature called Foxton that would have let the chip jump to 2GHz if it was running cool enough.
