Yeah, I don't really care that much about numbers. I care more about actual performance. iPhones have almost always had less RAM than the high-end Android phones, and they've still run smoothly. When the Moto X 2013 came out, there were folks saying the processor wasn't high-end enough, but it was also fine. The few videos I've seen of the Nexus 5x in action lead me to believe performance is fairly smooth (hopefully Marshmallow and whatever's coming down the pipe will optimize for the specs of Nexus devices).
