Mac-oriented Web site AppleInsider has uncovered a pic of Motorola's upcoming PowerPC G4 processor. We've known for some time that the new chip will be officially dubbed the PowerPC 7400, but it's good to get confirmation of the fact from the pic of chip itself. The chip also appears to be a 350MHz, which is rather less than Motorola originally predicted the chip would operate at. As an early version, though the final version should clock in in the 450-500MHz range. Equally interesting is the apparent doubling of the CPU's die size over the PowerPC 750 (aka G3). The die is inherently larger than the G3's but the new processor's AltiVec vector processing engine will be taking up a lot of the extra. The G4 is also manufactured at a smaller, 0.18 micron process than the PPC750, so the increase in die size is actually larger than it would appear. ® To view the G4, visit AppleInsider
