exynos chipset is very sluggish,not at all optimised and has a poor performance, cause overheating when used for a short while.This might be the answer of thousands of exynos haters(including me).
I like Exynos SOCs but Samsung has not optimised it properly in Budget M series and Mid range M series phones. It Supports CA but still samsung has disabled it. Samsung locks Camera2api and also doesn't provide sources for Custom ROM Development.
