That's a very difficult question to answer (hence the YMMV
disclaimers the automobile industry uses when claiming 150mpg for
The clock speed is a marketing gimmick. It may give you some
information on performance, but there is much more involved:
internal chip architecture (e.g., instruction pipeline depth)
blah blah blah
The dual core chip gives you multiple (2) processors, with some speed
and other advantages because they are on the same chip, but it
doesn't double the performance of a single 'do loop'.
Running a TeX compile will likely not need more than one processor,
but the fact that you have more than one will let other things go on
The TeX compile will more likely measure differences in disk and
memory bandwidth, and details of the chip architectures.

Anything we can do to simplify your life :-}. Once you get it, let
us know what the difference is ;-}
