YES!!! This was my main concern so far - the PX3 in the current crop of units is the exact same CPU architecture, with the same clock speed as the Samsung Galaxy SIII from all the way back in 2012.
If this is really PX6 it could be* incredibly more responsive.
* Unless the Chinese assembled a really shoddy Android image for it, of course.
