The performance difference between SP 820 and Exynos 8890 is more than expected
Samsung, again, introduced their flagship phones with both options; one with SnapDragon 820 and other one with their Exynos 8890. And, as you might expect, there is a performance gap between both of the versions.
I do like the Exynos processors, but to be honest, Snapdragon is better. In this case, I do not understand why Samsung makes two variants because if it was really up to the customers, they would choose the Snapdragon one. And the worse thing is Exynos 8890 is slower than Snapdragon 820.
As you can see in the graph, SP 820 is even better than the A9, but Exynos, unfortunately, is slower than A9. Actually, in the real world, you will not see the difference unless you are comparing two variants side by side.
For example, in Europe, you had to pay more than US to get a S7, but your phone will be slower since it has Exynos. That is the point that I hate about Exynos.
