  In the present paper, we explore various gravitational aspects such as energy
extraction (via the Penrose process and Superradiance), particle collisions
around a $\mathcal{N}=2$, $U(1)^2$ dyonic rotating black hole (BH) in the
gauged supergravity model. The impact of the rotation parameter ($a$) and the
gauge coupling constant ($g$) on the behaviour of horizon and ergoregion of the
BH is studied. It is of interest to note that, compared with the extremal Kerr
BH, the gauge coupling constant, under certain constraints, can enhance the
maximum efficiency of energy extraction by the Penrose process almost double.
Under the same constraints, we can extract approximately 60.75\% of the initial
mass energy from the BH which is noticeably higher in contrast to the extremal
Kerr BH. The limit of energy extraction in terms of the local speeds of the
fragments is also examined with the help of the Wald inequality. We identify an
upper limit on the gauge coupling constant up to which the phenomenon of
Superradiance is likely to occur. Finally, we computed the center-of-mass
energy ($E_{CM}$) of two particles with the same rest masses moving in the
equatorial plane of the BH. Our study also aims to sensitize $E_{CM}$ to the
rotation parameter and the gauge coupling constant for extremal and nonextremal
spacetime as well. Especially, for the extremal case, an infinitely large
amount of $E_{CM}$ can be achieved closer to the horizon which allows the BH to
serve as a more powerful Planck-energy-scale collider as compared to Kerr and
any other generalized BHs in the Kerr family explored so far in general
relativity. However, $E_{CM}$ for the nonextremal spacetime is shown to be
finite and has an upper bound.
