Yupp you are right and if anybody is wondering about the dual core:-Moto X has better screen and Gorilla Glass 3. Xperia 2013 phones had complaints of bad viewing angles and washed off screen.
Moto X has a X8 architecture. It has some less power consuming cores for small things like language processing, motion features.etc apart from a very powerful dual-core chip. The dual-core chip is a stripped down version of the snapdragon S4 pro processor. Unlike other phones which take all the processes under a single chip, the heavy applications work on the almost idle two dual core krait cpu's.
This is a very smart architecture which has impressed almost all the geeks.
Youtubers like Marquees Brownlee and Austin Evans are all fans of this phone.
