Yeah I've seen a couple of Quadrant scores from the units at the show. One of them was over 11,000 and one was a little over 8,000. One thing that came to mind, is if the S4 Pro thing is true, then that could account for the lower score, and the higher one could be the Exynos Octa; that is, if Samsung brought both kinds of models to the show because they needed as many as they could to demo. A low score could also be an issue with the test running with a low amount of memory available, could it not? Either way, 1.9GHz is 200MHz above the max factory clock of the APQ8064, but 1.9GHz is the max clock of the Snapdragon 600. I mentioned that in the comments on one of the news posts. I doubt Samsung would overclock a flagship phone that millions of people are going to buy. Could be some quality control issues with such a move.
