The centrality dependence of the charged-particle multiplicity densities (dNch/dη) and transverse energy densities (dET/dη) are investigated using the two-component Glauber approach for broad range of energies in heavy ion collisions at Relativistic Heavy Ion Collider (RHIC) and Large Hadron Collider (LHC). A comprehensive study shows that the data is well-described within the framework of two-component model which includes the contribution of "soft processes" and "hard processes" for different centrality classes and energies. The data at two different energies are compared by means of the ratio of dNch/dη· (and dET/dη) to see the interplay of energy scaling and relative contribution of hard processes.
