Speed does not equal processor power

A Ferrari is faster than a train, but which will get 100 tons of
freight coast to coast first?

after some interesting reading I found your answer
the eMac(ppc 7447a) does not have L3 cache, the powerbook(ppc 7455) does

The cpu speed only comes into play once the data is actually in the cpu
even though the emac has a substantially higher clock speed the
powerbook spends less time waiting for data to work on
even if you had a 40ghz cpu it would be slow if it took a second to
xfer data to the cpu

here are some links if you are curious
