  Let $\mathcal{A}$ be an abelian category. In this paper, we investigate the
global $(\mathcal{X} , \mathcal{Y})$-Gorenstein projective dimension
$\mathrm{gl.GPD}(\mathcal{X} ,\mathcal{Y})(\mathcal{A})$, associated to a
GP-admissible pair $(\mathcal{X} , \mathcal{Y} )$. We give homological
conditions over $(\mathcal{X} , \mathcal{Y})$ that characterize it. Moreover,
given a GI-admisible pair $(\mathcal{Z} , \mathcal{W} )$, we study conditions
under which $\mathrm{gl.GID}(\mathcal{Z},\mathcal{W})(\mathcal{A})$ and
$\mathrm{gl.GPD}(\mathcal{X},\mathcal{Y})(\mathcal{A})$ are the same.
