Seems good on paper but the rest of the internal components will stay the same in terms of speed and responsiveness, creating the already present bottlenecks. My old dual-core 1.0 GHz Cortex-A9 powered tablet is more responsive than the P78 with its every single way superior and faster hardware. Even an unresponsive and wasteful power-scaling governor can make or break a normally fine user experience and do not even get me started on the "did the touch layer registered my input or the system just hangs up for no particular reason for seconds" rant.
Don't get me wrong, any progression is good but there are several other parts (hardware and mostly software optimization) where development could reap much more benefit than just slapping a faster processor into the chassis and call it a day. Sadly, a small market like this can't really gather enough world-class developers and engineers to solve these hard problems.
I'd say if somebody wanted to buy the vanilla P78 then go for the P78pro instead (the price is kinda the same anyway) and expect a little better but not world-shattering extra performance if your use-case can take advantages of it.
