I can explain a few differences for you.

The core speed for 645 is 823Mhz, but the core speed for the 660 is 980MHz so obviously the 660 wins in terms of core speed.

The memory speed for the 660 is 2048mb, but the 645 has a 1024mb memory speed.

Instead of me explaining the differences (theirs quite a lot) you can click the link below and check more of the differences out.
