Intel claims that when single threaded apps or multi-threaded apps with extended serial code are executed, IDA gives additional performance benefits.More details at The Inq. Another new thing is that Intel will add support for a graphics render clock frequency for its Crestline GM chipset within current power ratings to improve performance in Windows Vista's new Aero interface.
One core puts its feet up while the other one works like a donkey, with IDA active only when one bit of code is up for execution. Meanwhile, multiple apps can be open and hang around smoking tabs and gossiping around the water cooler.
The Santa Rosa L7500, L7300, U7600 and U7500 CPUs will all come equipped with IDA.
In Norse mythology Ida is a mythical plain on which Asgard (the realm of the gods) is built. In Stargate (a TV show some of you will probably know), Ida is the home galaxy of the highly advanced Asgard race.
