As an offshoot to the Intel / AMD quarrel I had to do a post on the undoubtedly best processors in the market...

This is taken from the October MAC World

G4 G5
Clock Speed 1 - 1.42 1.66 - 2
Pipeline depth 7 16
Maximum execution 3 4
Integer units 4 2
Floating Point units 1 2
SIMD units 4 4
Front-Side Bus 167MHz up to 1GHz
Memory Bandwidth 1.3GB per sec 8GB per sec (16 in dual)
Maximum System Memory 4GB 8GB


my addition
RAM specs up to PC 3300 up to PC4200


Though the G4 has more integer units (4) .. the G5 does higher bit calculations per second per unit thereby validating the reduction in integer units ;D
