We present the analysis of the complete glueball spectrum for the AdS(7) black hole supergravity dual of QCD(4) in strong coupling limit: g(2)N --> infinity. The bosonic fields in the supergravity multiplet lead to 6 independent wave equations contributing to glueball states with J(PC) = 2(++), 1(+-), 1(--), 0(++) and 0(-+). We study the spectral splitting and degeneracy patterns for both QCD(4) and QCD(3). Despite the expected limitations of a leading order strong coupling approximation, the pattern of spins, parities and mass inequalities bare a striking resemblance to the known QCD(4) glueball spectrum as determined by lattice simulations at weak coupling.
