201_ PowerPC 7451/667 and Rev. 11 Uni-North IC memory performance
The determination of memory performance of PowerBook G4 Gigabit Ethernet was difficult.
L1 performance measured memory transmission competence of 4,8,16Kbyte entity.Content was small, but, as for L2 cash built in by die internal, performance improvement more than clock rate was recognized.
The memory bus performance that uped from 100 MHz to 133 MHz improves as expected, too.
