To compare real-life RAW performance on the Canon EOS T3 / 1100D, I shot this scene using RAW plus Fine JPEG mode at the camera's base sensitivity of 100 ISO.

The EOS T3 / 1100D was fitted with the EF-S 18-55mm III, set to f8, and the focus confirmed with magnified assistance.

The image opposite was taken with the Canon EOS T3 / 1100D at 100 ISO with an exposure of 1/640 and the lens set to 21mm f5.6; the original Large Fine JPEG measured 5.22MB. The crops below are taken from the areas marked with the red squares and presented here at 100%.

I processed the RAW file from the T3 / 1100D with Canon's supplied Digital Photo Professional software, using the default settings (Unsharp Mask 3 / 7 / 1). The only change I made was to select Chromatic Aberration correction in the lens section.

The impact of the Chromatic Aberration reduction is immediately apparent, with the RAW conversion delivering a much cleaner-looking result, bereft of the coloured fringing which plagued the in-camera JPEG around areas of high contrast.

As to the actual detail, sharpness and contrast, the two files look pretty similar. There's arguably a small edge to the converted RAW file, thanks no doubt to its more refined Unsharp mask process, but otherwise the two images aren't a world-apart.

As always, the benefit of shooting RAW is the ease with which you can apply and change settings like the White Balance, not to mention retrieving greater tonal detail, but using the default settings on Digital Photo Professional with the T3 / 1100D won't yield significant differences over in-camera JPEGs. If you only make one change though, tick the box to enable correction of Chromatic Aberrations - in images like these, it's one of the best reasons for shooting RAW.

Okay, that's enough for the outdoor test composition now: let's move on and check out the High ISO performance in my T3 / 1100D vs D3100 noise results.
