Yonah T2600 at 2.16 GHz: PowerBook.
Early next year, intel will release their Yonah line of mobile CPUs to the public - and Apple will apparently be a part of this launch according to our sources. According to them, Apple will release both an intel iBook as well as an intel PowerBook in the first quarter of 2006 already, despite previous assumptions that Apple's intel hardware would have to wait until mid 2006.
The Yonah processor family to debut as both a dual core and a single core variant. Top of the line will be the T2600, a dual core processor clocked at 2.16 GHz. There's also going to be versions clocked at lower speeds
(T2500, T2400 and T2300 at 2, 1.83 and 1.66 GHz) as well as single core versions (T1300 at 1.66 Ghz would fit the iBook) and low power versions (L2500, L2300 etc.). The first intel-based Macintosh products could very well be announced at MWSF in January, although the iBook's processor variant is believed to be introduced only later in the quarter by intel.
