Comparison of characteristics

It is difficult to give a verdict on this point because of the difference between the three processor smartphones. But what we can say is that the Galaxy S4 is the most powerful with a 5 Octa Exynos 1.8 GHz Qualcomm Snapdragon 600 or a quad-core clocked at 1.9 GHz. The Z10 is equipped with a modest effect Qualcomm Snapdragon dual-core 1.5 GHz Krait iPhone 5 and an A6 1.2 GHz.?
