  We analyze the running at one-loop of the gauge couplings in the spectral
Pati-Salam model that was derived in the framework of noncommutative geometry.
There are a few different scenario's for the scalar particle content which are
determined by the precise form of the Dirac operator for the finite
noncommutative space. We consider these different scenarios and establish for
all of them unification of the Pati-Salam gauge couplings. The boundary
conditions are set by the usual RG flow for the Standard Model couplings at an
intermediate mass scale at which the Pati-Salam symmetry is broken.
