There are a lot of gaps spotted in the naming convention of Samsung. There is the Samsung A5, A7 but no A6, until now that is. Two Samsung devices have been spotted in the GeekBench with SM-A600FN and SM-A605G, which possibly translates to the names: Galaxy A6 and A6+.
Based on the results from, the difference in performance of these two are not that far from each other. The Samsung Galaxy A6 will use the Exynos 7870 which can be seen in several J series phones, while the Galaxy A6+ will have a Qualcomm Snapdragon 625. Both devices utilize an eight-core chipset, with the plus version sporting more RAM. Infinity displays? probably.
