C/C++ can also produce data structures that are more compact than any managed language could allow. For example, one of the oldest tricks in raytracing is to stuff a few bits of information into the lower bits of a float, so that you don't have to waste a whole byte encoding the metadata for a kd-tree node. But even this is ultimately related to speed. It allows the programmer to squeeze a whole lot into a cache line.
