Graphics And Memory
The Galaxy Tab S is by far the most responsive Android tablet we've ever tested. Samsung's flagship slabs are built around its flagship SoC: the Exynos 5 Octa 5420, an eight-core powerhouse with four 1.9GHz ARM A15 Cortex cores and another four 1.3GHz A7 Cortex cores. Also inside is the ARM-based Mali-T628 MP6 GPU, which Samsung says more than doubles the 3-D graphics capabilities of its predecessor. GTS devices come with 3 GB of LPDDR3 RAM for running apps and either 16 or 32 GB for storing them. There's also a microSD card slot that supports as much as 128 GB of additional storage.
