Some of the early RDF Graph Stores were indeed based on SQL databases (Jena RDB/SDB) but you're correct in that they didn't scale particularly well.
There are pure graph stores out there, AllegroGraph, OpenLink Virtuoso (although this is a strange hybrid of SQL + Graph technologies) and others - and for more advanced graph query constructs like path finding there are optimisations that are difficult/not well supported in SQL.
