What's the difference between differently named models that run the same GPU?

For example, the GT 745M and GT 750M are both based on GK107, with the same number of cores, TMUs and ROPs (384, 32, 16). Both come in GDDR3 and GDDR5 versions.

As far as I could tell, the only difference is clock speed. Am I missing something?

There are usually different technologies lying in each card, like the higher model may have higher clocked RAM.
Frankly, you are right that the only difference is clock speed.
