After months of teasing, Samsung has gone official with the Galaxy Tab S lineup. Their new tablet range brings back AMOLED displays to large-screen devices, namely Android-powered tablets. Both devices come with WQXGA (2560 x 1600) Super AMOLED displays that boast 90% Adobe RGB color coverage.

　　Samsung's Galaxy Tab S 10.5 has a 10.5-inch panel, weighs 465g, has a large 7,900 mAh battery and is just 6.6mm thick. Meanwhile, the Galaxy Tab S 8.4 has a 8.4-inch panel, tips the scales at 294g, has a smaller 4,900 mAh battery and is also 6.6mm thick.

　　Both tablets are powered by either the Exynos 5 Octa (4 x ARM Cortex A15 clocked at 1.9 GHz, 4 x ARM Cortex A7 clocked at 1.3 GHz) or the Snapdragon 800 (2.3 GHz), depending on the region. There's 3 GB of RAM, 16 or 32 gigs of expandable storage, a microSD card slot, BT 4.0 and optional LTE connectivity. Also, both slates have the new fingerprint reader, which debuted on the Galaxy S5 earlier this year. The software side is covered by TouchWIZ based on Android 4.4.2 KitKat. There's 8 MP rear and 2.1 MP front cameras as well, on either slate.

　　Samsung also announced two accessories for either tablets - Bluetooth keyboard and a Book Cover.

　　The starting price of the Galaxy Tab S 10.5 and Galaxy Tab S 8.4 is $499 and $399 respectively. While AT&T, Sprint and T-Mobile will only offer the 10.5" slate (with LTE), Verizon will offer the 8.4" tablet in addition to the 10.5" version. Global variants of the new Galaxy Tab S range are expected to go on sale later this month.
