The Samsung Galaxy Tab S3 is on its way to replace the 2015 Tab S2, and more information is now available regarding its specs and design.

While Samsung has yet to make an official announcement, all signs point to an imminent debut. Not too long ago, the Galaxy Tab S3 crossed the FCC in the United States, suggesting that a U.S. unveiling was just around the corner.

Now, the tablet just dropped by TENAA as well, which is the Chinese equivalent of the FCC. Such certification bodies are typically among the last stops before a product hits the market, so the Galaxy Tab S3 could become official any time now.

The TENAA certification not only offers images of the device to show off its design, but also includes details on the tablet's core specifications.

The upcoming Galaxy Tab S3 is expected to arrive in 8-inch and 9.7-inch versions, just like the Galaxy Tab S2 from last year. The Galaxy Tab S3 8.0 has model number SM-T719C and it looks quite similar to the Galaxy Tab S2 8.0, sporting the same design, dimensions and weight.

The difference is under the hood, however, as the upcoming Samsung Galaxy Tab S3 8.0 will pack an octa-core Snapdragon 652 processor clocked at 1.8 GHz, as opposed to the Galaxy Tab S2 8.0's 1.9 GHz Exynos Octa 5433 processor.

Other specs remain largely unchanged, with the Galaxy Tab S3 8.0 featuring an AMOLED panel with a resolution of 1,536 x 2,048 pixels, 3 GB of RAM, an 8-megapixel main camera, a 2-megapixel front camera, 32 GB of internal storage (expandable), and a 4,000 mAh battery.

On the software side of things, the new Galaxy Tab S3 8.0 will rock Google's latest Android 6.0 Marshmallow out of the box.

Other than the different processor and the newer OS version, however, the Samsung Galaxy Tab S3 8.0 doesn't really seem to be a major upgrade from last year's model.

It remains unclear for now just when it will officially break cover, in which markets or how much it will cost, but it should all become clear soon enough. We'll keep an eye out for Samsung's announcement and bring you the latest news as soon as they become available, so stay tuned.
