Samsung is expanding its Galaxy Tab 3 line, announcing the addition of 8 and 10.1-inch models to go along with the previously announced 7-inch device. This should help it better compete in the constantly growing tablet market, with more options to offer potential buyers.

The 8-inch version of Samsung's Galaxy Tab 3 includes a powerful 1.5 GHz Exynos dual-core processor, 1.5GB of RAM, and a 1280 x 800 screen resolution that equates to 189PPI. It also comes with a 5-megapixel rear-facing camera, complemented by a 1.3-megapixel unit on the front for video chats, and a 4,450 mAh battery.

The 10.1-inch variant is actually quite different in terms of specs. While Samsung didn't actually reveal the type of processor in its announcement, it's widely believed to be 1.6 GHz dual-core part from Intel. The tablet features the same 1280 x 800 resolution as the 8-inch model, which means it has a lower PPI at 149, and as you might expect it sports a bigger 6,800 mAh battery to support the power demands of a larger screen. 

The 10.1-inch model is actually lacking next to its smaller sibling in a couple areas. It has 1GB of RAM, down from 1.5GB, and while its front facing camera is the same, the rear unit is only 3-megapixels. 

Both tablets come with Android 4.2.2 Jelly Bean installed and the latest TouchWiz applications from Samsung. They will be available in both 32GB and 64GB internal storage vartiants, with the option to expand storage via microSD, and come in Wi-Fi, 3G and 4G versions starting later this month.

Unfortunately, no pricing details were given for either model at this point.
