I was under the impression it was as much about sensor size as
anything. If you have a large sensor ( as in the D50 ) then the wee
image capturing[0] things weren't as wee and hence were a bit more
sensitive and so overall image quality was better.

This has a lot about that sort of thing:

Of course, the fact that RAW isn't compressed in a lossy format and
so on also helps.
