Motorola, The G4 and PowerBook Updates

The new chip from Motorola (announced in February) increases the L2 cache as well as the L3 cache and provides a max speed of 1.3GHz -- and incorporates a 200MHz frontside bus, allowing for DDR400 support.
The Register expects this chip to be the most likely processor for the upcoming PowerBook.
This is consistent with one unverified rumor that upcoming PowerBooks come in at 1.3GHz.
