No in real word performance it's far behind. ARM is way less efficient that x86.
So yeah, my dad wants it because he wants a huge phone, because he doesn't like carrying around a phone
and a tablet. He's not satisfied with 5 inch screens and the Note 3 is like 2 or 3 times as expensive so the 1+1 obviously got his attention. He'd be pretty happy if I got him the invite.
I don't have much more to say, this phone's awesomeness is universally recognized.
