Samsung today announced two new AMOLED tablets, the Galaxy Tab S2 9.7-inch and Galaxy Tab S2 8-inch. Both tablets adopt QXGA (2048x1536) Super AMOLED displays (263 PPI on the 9.7" and 320 PPI on the 8").

Those AMOLED displays are actually of lower density than those used in the first-gen Tab S tablets (which were WQXGA, or 2560x1600 or 287/359 PPI). Samsung however says that the Tab S2 OLEDs are "newly optimized" and deliver 94% of the Adobe RGB standard for true-to-life colors. The new aspect ratio (the tablets are not as wide as the Tab S ones) is better for reading, too.

Other features of the new tablets include an octa-core CPU, 3GB of RAM, 32/64 GB of internal storage, 8MP rear camera, LTE (on some models), Android 5.0 and a 5,870/4,000 mAh battery. Samsung says that these are the thinnest (5.6 mm) and lightest (389/265 grams) metal-framed tablets on the market.

Both tablets will launch in August 2015, in either Wi-Fi or LTE and Wi-Fi models. Prices aren't available yet.
