The Samsung Galaxy Tab 3 is finally on sale in the U.S. in all its 7-, 8- and 10.1-inch models, sporting attractive price tags and specs.

Samsung and Amazon are already selling the tablets in the U.S., so here's all you need to know about pricing, specs and features.

According to the official Samsung website, the 7-inch Galaxy Tab 3 sports a 1020 x 600 resolution LCD display and a 1.2GHz dual-core processor under the hood, along with 1GB of RAM. The slate comes with 8GB of internal storage and a micro SD card slot for additional memory of up to 64GB. This model costs $199.99 and ships with Android 4.1 Jelly Bean on board.

The 8-inch Samsung Galaxy Tab 3 offers slightly better specs than its little brother, sporting a 1280 x 800 resolution display and a more powerful 1.5GHz dual-core processor with 1.5GB of RAM. Storage is also double on this model, i.e. 16GB, with a micro SD card slot allowing for up to 64GB of additional storage. While the spec bump is not very substantial, this model seems to be the best in the lineup and it ships with the latest Android 4.2.2 Jelly Bean right out of the box. The price, however, goes up to $299.99.

Lastly, the 10.1-inch Galaxy Tab 3 has the same 1280 x 800 resolution display as its 8-inch sibling, which makes it considerably less impressive compared to the Nexus 10, for instance. This model has a dual-core Intel Clover Trail+ processor clocked at 1.6GHz and only 1GB of RAM. It packs 16GB of internal storage and a micro SD card for additional memory of up to 64GB, all for $399.99. The Galaxy Tab 3 10.1 ships with the latest Android 4.2.2 Jelly Bean as well.

It's also worth mentioning that all three tablets sport a physical home button similar that found on Samsung's smartphones, marking a notable change from the Galaxy Tab 2 line-up. All three Galaxy Tab 3 models come in two color options: white or golden-brown.

The tablets are currently available from Samsung and Amazon, but more retailers should offer the Samsung Galaxy Tab 3 lineup soon enough.
