The difference is that core 2 supports SSSE3-instructions and nocona doesn't.
There is a series of mails starting with
<http://gcc.gnu.org/ml/gcc-patches/2006-11/msg00860.html> about the tuning of
gcc to core 2, which - if I understand it right - shows improvement for
integer
calculations and nearly no difference for floating point calculations. Not any
extreme differences but some improvement.
