From the RAW image we can see just how much noise the camera's processing is having to deal with, even at ISO 800. The noise is mostly chroma noise, which is going to be noticeable even in small prints, but is fairly easily removed in post processing. Whether you'd end up with anything considerably better than the out of camera JPEG results is questionable (there's certainly a little more detail in the ISO 1600 RAW file than you get in the JPEG, but it is pretty much swamped in noise).
