What i heard is the Nucoda system uses CPU and GPU for calculation. Especially when calculating CPU intensive DVO effects like de-grain and dust removal, the CPU will be used quite fully. The floating points calculation of CPU is more accurate than GPU, so what I am told is the resulted images are even better than the DVNR. Another benefit of such combination is the software speed is not limited to hardware expansion such as you will have limitation in adding number of graphics card.
