Technical - RAW and JPG compared (LEE)

I found an experiment to compare RAW and JPG file in a Korean DSLR Club.
They took this picture RAW and JPG each and compared three different spots.

The picture below is the spots compared.

So they concluded that if they take a photo in RAW, it is very clear and less blurred than JPG but there might be more noises.  The real difference between RAW and JPG is if the phoro is processed or not but there can be this kind of difference.
