I'm afraid, that it's not that simple. As far as I
understood, the low cost thumbs are running with
32 bit access in internal memory only. Having Nut/OS
and the application in on-chip RAM is an advantage.

Another thing is, that total cost is also based on chip
count and PCB size.

On the other hand, external flash gives more flexibility.
It may contain the image _plus_ a file system.
