Quantum chemistry software benefits from 'stupid-high bandwith RAM'. It says Gaussian supports this hardware. I remember when running VASP (another popular quantum chemistry software) we were not even using all the cores on a node, because the limited performance of the RAM interface. The basic operation they perform is fast fourier transform on large (number of electrons of the system ^ 2) matrices.
