New iMacs running an overclocked Penryn chip, not Montevina

Following this morning's iMac introduction, speculation has been rampant as to whether Apple got an early shot at Intel's upcoming Core 2 Duo Extreme X9100 chip. The X9100 is meant to usher in the "Montevina" Centrino 2 era, and boasts significant less power consumption than its forebears, in addition to those spiffy new clock speeds. Well, it turns out the new iMacs aren't Montevina, but instead a special-made 45nm Penryn 3.06GHz chip with a 1066MHz frontside bus. That means most of the juice of the X9100, but at 55 watts instead of 44. This chip exclusivity has been a bit of a pattern with Apple, and one which we're sure its competitors are quite appreciative of.
