SAN FRANCISCO--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 major reason for the lower power is the shift to a new manufacturing
process employing 90-nanometer features, which means the circuitry can
be made smaller compared with the 130-nanometer size used by the current
Itanium, McLaughlin said. (A nanometer is a billionth of a meter;
Intel's PC processors are already produced on a more advanced process
with 65-nanometer features, and the chipmaker just demonstrated a
prototype with 45-nanometer features.)
....
But part of the lower power consumption came because Intel sacrificed
features and clock speed in an October delay of Montecito, Krewell said.
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. "It's disappointing that something they hoped
would provide a greater kicker couldn't be there and that they delayed
the launch for nine months to close to a year," Krewell said.
------------------
Question: Since that IA64 is finally going dual core, will VMS licencing
get any changes ?
>From an OS point of view, I take it they will need to wait for the next
release of VMS to support this new chip ? Or is the chip coing to be
functionally identical to existing IA64 things and support 8.2 out of
the box and appear like a machine with 2 separate CPUs ?
