Without necessarily getting into information theory too deeply we can see that computation has some impact on the information theoretic scale of a system. An easy example is SU(2) vs SU(3). SU(2) has one weight, corresponding to two eigenvalues, and two roots that act as raising and lowering operation on the weight. This is seen in the standard spin model of fermions. The SU(3) model has two weights with three values, corresponding to the 3,3-bar representations of color charges, and 6 roots that transform between the weights. This has more computation and also more degrees of freedom. So the more computation there is, where a Feynman diagram could be thought of as a succession of operations or computations that raise or lower various quantum numbers by exchanging with other quantum numbers, the more degrees of freedom there are.
