  In our study, we examine a 2D radiation, relativistic, magnetohydrodynamics
(Rad-RMHD) accretion flows around a spinning supermassive black hole. We begin
by setting an initial equilibrium torus around the black hole, with an embedded
initial magnetic field inside the torus. The strength of the initial magnetic
field is determined by the plasma beta parameter, which is the ratio of the gas
pressure to the magnetic pressure. In this paper, we perform a comparative
study of the `magnetically arrested disc (MAD)' and `standard and normal
evolution (SANE)' states. We observe that MAD state is possible for
comparatively high initial magnetic field strength flow. Additionally, we also
adopt a self-consistent two-temperature model to evaluate the luminosity and
energy spectrum for our model. We observe that the total luminosity is mostly
dominated by bremsstrahlung luminosity compared to the synchrotron luminosity
due to the presence of highly dense torus. We also identify similar
quasi-periodic oscillations (QPOs) for both MAD and SANE states based on power
density spectrum analysis. Furthermore, our comparative study of the energy
spectrum does not reveal any characteristic differences between MAD and SANE
states. Lastly, we note that the MAD state is possible for both prograde and
retrograde accretion flow.
