Sad thing about that is the iPhone 5s kicks that 8 core samsung phones ass in benchmarks. And the 5s does it without doping the processor with os tweeks like GS4. And by the way the exynos 8 core only uses 4 cores at a time stock. It either uses the 4 stock a15 arm cores high power mode or the 4 stock a7 arm cores low power mode. Samsung is using ARM's Big Little architecture to put 8 cores together.You really need to research more before you post.
