For any ring $R$, we show that, in the bounded derived category
${{D}^{b}}(\text{Mod}\,R)$ of left
$R$-modules, the subcategory of complexes with finite Gorenstein projective (resp. injective) dimension modulo the subcategory of complexes with finite projective (resp. injective) dimension is equivalent to the stable category
$\underline{\text{GP}}(\text{Mod}\,R)\,(resp.\overline{GI}(Mod\,R))$ of Gorenstein projective (resp. injective) modules. As a consequence, we get that if
$R$ is a left and right noetherian ring admitting a dualizing complex, then
$\underline{\text{GP}}(\text{Mod}\,R)$ and
$\overline{\text{GI}}(\text{Mod}\,R)$ are equivalent.
