How does the D3 achieve such high ISO?

Very simple: LARGE photo-sensitive area and MASSIVE N.R....

...The massive N.R. piece applies to .JPGs, at the expense of overall sharpness and image quality (as all samples, images and conversions that I have seen/worked-with from the D3 indicate).

As for true RAW data, I have seen plenty of ISO6400 that do not really impress me at all (that is, YES, from a pure technical point-of-view, but NO in light of the "hype").

Here is just one of them:

And, just to give you an idea of what happens with D3's on-board .JPG cooking, check this example on how that technology actually does wonders on MUCH less-capable cams (I had access to both .JPG and RAW files on this example, camera RICOH GRD2, from-cam-.JPG on the left, and my best LR conversion, on the right):

As you can see, the Ricoh GRD2 is using an on-board NR technology that yields in REMARKABLY SIMILAR-LOOKING files and output as the D3 does with its .JPGs.
