Don't forget that in addition to comparing the speed of these two
processors, you are comparing their instruction sets as well. This is
borne out by the fact that the speed difference between the two
machines is not a constant ratio.
The mac is a RISC machine. The PC is a CISC machine. In some cases the
slower processor will do as well as the faster one because of the
microcoding for mathematical, as well as other (bitblt, etc)
operations.
Other factors, such as pipelining and caching (L1, L2, etc) will have
an effect as well.
As I recall, some of the Macs had FPUs, and others did not. This will
also affect the speed.
