Is the value of the determinant of a large matrix the same as the value of the determinant of its chunked matrix?

Question

An $8 \times 8$ matrix $M$ is directly computed by computing its determinant $|M|$, and by dividing it into blocks $ M = \left [ \begin{matrix} A & B \\ C & D \end{matrix} \right ] _{4 \times 4} $,$A, B, C, D$ are the $2 \times 2$ matrix, compute determinant value of $ \left | \begin{matrix} A & B \\ C & D \end{matrix} \right | _{4 \times 4} $, are these two values the same?
