It seems you haven't read the documentation :-), i can understand that, I 
always try to do without it.
The thumbnail and preview of RAW files use the RAW-embedded thumbnails which 
are identical in conversion but smaller than the jpeg files. 

There is no interest to produce jpeg equivalents with RAW files (otherwise 
shot in jpeg mode). The RAW conversion aims at achieving something 
else/better than jpeg camera processing. In order to get that to work you 
have to set up the RAW conversion (with appropriate color profiles) and color 
management in the settings pages. Please refer to the documentation for 
details.
