The Samsung Galaxy A7(2016) in our office has a Snapdragon 615 chipset. Inside are eight Cortex-A53 cores next to an Adreno 405 GPU. They are connected to 3GB of RAM, a bump over the A5(2016) and the old A7. It's still essentially the same chipset, though.
There's a version with Exynos 7580, which has the same basic setup, except a Mali-720MP2 takes over the GPU duties.
Again, we're testing the Snapdragon 615 version.
