The Samsung Galaxy Tab S 10.5 and Galaxy Tab S 8.4 offer the best of Samsung in the tablet department, mixing its experience with making Super AMOLED smartphones and tablets with octa-core processors into one product line. The Galaxy Tab S tablets come in at a radically thin 6.6mm and have ultra-high resolution 2560x1600 displays, Samsung's octa-core Exynos processor, 3GB of RAM and a design language that mimics the Samsung Galaxy S5.
