As the TENAA photos from early May revealed, the Samsung Galaxy Tab 3 8.0 doesn't come with any significant design or build differences when compared to its direct predecessor.
According to previous leaks, the Samsung Galaxy Tab S3 8.0 will draw its processing power from a Qualcomm Snapdragon 652 chipset, a mid-range SoC that includes four Cortex-A72 CPU cores, four Cortex-A53 CPU cores, and an Adreno 510 GPU. Other hardware specs are expected to include 3GB of RAM, 32GB of integrated storage, an 8MP primary camera, as well as a 2MP selfie sensor on the front. On the software front, the Galaxy Tab S3 tablets are expected to run Android 6.0 Marshmallow out of the box.
As was the case with the previous tablets in Samsung's Galaxy Tab S line-up, the Galaxy Tab S3 series is expected to feature high-resolution Super AMOLED panels. Leaks suggest that both the 8-inch and the 9.7-inch versions of the Tab S3 will make use of a 2048 x 1536 display resolution.
Looking at the leaked specs and photos, it looks like the Samsung Galaxy Tab S3 series will be nothing more than a slight upgrade over the Tab S2. However, there is hope that the Adreno 510 GPU inside the Snapdragon 652 will be better able to cope with the high display resolution than the Mali-T760 MP6 GPU featured by the Tab S2, which was one of the major drawbacks of the previous generation.
Given the rate at which Samsung Galaxy Tab S3 leaks are surfacing online, chances are that an official unveiling is right around the proverbial corner.
