The Samsung Galaxy Tab 3 10.1 has a 10.1 inch screen with the same 1280 x 800 resolution, which means a lower pixel density than the 8 inch model. A dual-core 1.6GHz processor is driving Miss Daisy with 1GB of RAM and a 3MP camera on board. A whopping 6800mAh cell is generating the power.
Samsung has not announced availability of the two slates in this color yet, but considering that you are looking at the tablets wearing the gold-brown color right in front of you, there is no reason to believe that the Korean OEM won't soon make the announcement. In the meantime, you can check out the slideshow below to view the two devices wearing gold-brown.
