I disagree. (surprise surprise )

I've probably tested 2-3 dozen KAF11000 series sensors (no prizes as to which manufacturer) and have seen significant variation in the noise from chip to chip....ie all chips are *not* the same.

I have noticed Kodak seem to be continually improving the noise performance of their sensors, eg. 2009 sensors look much cleaner than those manufactured in 2006.

However, the only accurate way of testing "off chip" noise variations across manufacturers would be to place the same chip into differing heads, then measure the result.
