Yes all of the information is in the link above (the link is however, broken, due to the missing last parenthesis).
In summary the Snapdragon in the Inc was a very early one, so called 1st generation. It uses an older manufacturing process that dictates how small the semiconductor feature sizes can be. The 2nd generation process used for the TBs chip not only allows a smaller chip but it improves on power consumption. Qualcomm has stated a 30% improved dynamic power consumption for the 2nd gen chips as well as a greatly improved idle power consumption (that detail not from the wiki page...)
Inc's Snap also uses an older graphics system (lower performance) Adreno 200 vs. Adreno 205.
There are also a slightly different set of wireless technolgies supported between the models.
