The answer is right there, in front of your eyes...

...Even without my opinion, try something simple (anyone can do it, indeed):
1. Go to the latest DPR T1i review, and jump to the ISO comparison section.
2. Go to the .JPG section (right at the top of the page), and FOCUS on the following three samples:
3. LOOK at the actual face-detail shown there at ISO100, and then quickly roll your mouse cursor over the ISO1600 label.... and you will notice (contrary to DPreview's own comments) that it is the 450D showing the overall best, most detailed image among ALL the cameras, followed by the T1i, and then following by mush-factory, Nikon D5000 (this is unquestionable, it is right there for everyone to see)...
Now, here comes the tragic part: do the exact same pan, as described above,but for the RAW samples, just scrolling down a bit on the same page, and roll over the ISo100 label, and then over the ISO1600 label... What do yo see? Exactly same results as above: 450D comes out strongly detailed, sharper (higher image integrity), then followed by T1i, and then (again) followed by even same mush-factory, Nikon D5000 (this is very, very strong indication that Nikon ***RAW*** files are all crooked/massaged with heavy-metal noise-reduction, on-board).
Answer to your question: LOTS of marketing and LOTS of on-board Noise Reduction (which is highly tuned for the camera's output, but not on par to what you can get from DiGiCIII output, and equally dedicated/tuned Noise Reduction).

But I also carefully read the threat where PIXmantra clearly explains that with careful (and tedious) post processing he gets much better results from his 1DMKIII than any Nikon and he states that the Canon Cmos sensor & Canon Digic Processor combo has a much better image handling.
(I do realize he referred to the 1D) see the thread (
...The purpose of a tool like FlexNR is to remove the word "tedious" and replace it with "one-click" for everyone, and leave only one person with the "blunt" of the work (that is me... ).
Now, you can rest assured the 1D3's on-board output (DiGiCIII .JPGs or conversions with RIT/ZB) already allow the camera to achieve unseen results, from the camera itself, and/or any other camera currently available, in the high-ISO department (and all this, mind you, with native ISO100 support, all the way to ISO6400, which is still analog-output from the 1D3 sensor, and not pushed digitially... ):
IS6400 1D3-vs-D3, .JPGs (from Imaging Resource, which I always recommend):
(look at the red cloth, the black mug, deeper shadows, and green plastic leaves)
And here is a simple, ISO12800 sample from the 1D3 (via RIT/ZB but otherwise identical to .JPG output, upward compensated +1.00ec), taking advantage of the unique spectral composition of .JPGs/RIT output (DiGiCIII):
