Those are not two distinct classes. A Geographical DBMS might be defined as any DBMS that has special support for geographical data in terms of querying, indexing and representing. So it could be an extended RDBMS or OODBMS, or ORDBMS, or something else entirely. In fact the extension might even stay within the particular paradigm of the DBMS and for example for the relational model define only a few extra domains with special operators. So it is a bit as if you are asking how convertibles compare to Mercedeses.
