Sawtooth, as some are already familiar with, is the code-name for Apple\'s \"next-generation\" Power Macintosh logicboard, rumored to ship with the G4 processor. The board, like the one inside Apple\'s iBook Consumer Portable, is based on Apple\'s new Single Common Unified Architecture. These boards can often be distinguished by the presence of AGP (an Advanced Graphics Port), among other things. The iBook and next-generation iMac (code-named Kihei) will ship with support for 2x AGP, while the Sawtooth hardware, aimed at professionals, will feature a 4x AGP slot.
