How does the D3 achieve such high ISO?

Re: Reduce your 1DsIII image to 12MP (about 50%)

Well, in the last issue of french magazine "Chasseur d'images", they
compare the results on same size print for D3 and 1DS3 at 1600 ISO.
The 1DS3 wins with head and shoulder.
They rate the 1DS3 at 185 against 137 for the D3.
More resolution helps a lot when big prints are the goal. And big
prints is what matters, after all, isn't it ?

To be honest, 1600ISO seems the limitation for the 1DS3 however.
Above that, the D3 seems to perform better. They don't give a figure
for higher sensitivity.
They probably will in the future, as it's their brand new high ISO
resolution test...

I guess that why Canon has the 1DsX and 1DX/5D serieses. The first one gives you the absolute best resolving power while the latter pair is better suited for low light (5D taken here only becvause it shares the sensor properties with 1D2).

If rumored "5D2" share the same sensor structure as 1D3 then we can expect a 16MP FF camera with similar low light performance, and thus about same performance as D3.
