The way I understand it is that the DSLR only has 1 red pixel out of every 4 pixels (ie 3/4 of a red frame is holes the between the active pixels) The mono chip with a red filter has every pixel active. The deBayering process guesses what might be in the holes in the DSLR RGB frames, but it doesn't have as much information to go on as the mono.

Of course the mono also allows you to record a luminance image (RGB added together) using all available photons and pixels, which is how it gets its main advantage.
