that's why they are different.

They are not "completely different". The A700 and D300 are using the same basic "IMX021" sensor which uses column parallel delta encoded A/D converters arrays fabbed directly into the sensor silicon. At best, the only difference with the D700 is the ability to let the A/D converters quantize in 14 bits. For delta encoded ADCs that might require no additional logic at all, because they are basically just counters, and to quantize to a higher bit count only requires more counting (given there is enough accumulator and counter register width and DAC precision). It is also completely consistent with the reduced frame rate the D300 can achieve in 14 bit mode.

If there are differences between the D300 and D700 quantization circuits, all indications are that they range between minimal and non-existent.

Some more about the sensor can be found here.
