The exynos in the N10 is a odd ball, pretty much every other device uses the octa core version.
Well, the number of cores, alone, doesn't affect the architecture much at all from an OS or app perspective. It is a Cortex A15 like every other Exynos that as come after it as of this writing. So it is hardly "odd". It didn't require any special coding. Even the graphics chip (Mali-T604) is not that unusual and should be forward compatible with the newer chips.
And as an aside- the newer chips are 4+4 cores, not 8 cores (huge difference, 4 are full speed, 4 are low speed, they are not all used at once). And 4 cores of the same type on a
tablet vs. 2 won't usually show much difference from a user real-world-performance perspective. For example, the Exynos 5410 might actually seem slightly SLOWER to the user than the 5250 in the N10 because it has a lower clock speed (in reality, it will probably seem to be the same speed).
The newer chips will use less power, for sure, since they are all 28nm instead of 32nm and also include those lower power A7 cores and improvements in the GPU.
