Besides the new Kindle and Fire HD tablets, Amazon also revealed an updated Fire HDX 8.9 tablet with faster internals, better audio and network performance and Fire OS 4.0. 

The Fire HDX is among the first Android tablets to feature an Snapdragon 805 processor and an Adreno 420 GPU. The 8.9-inch display has a resolution that is higher than the iPad with a pixel density of 339pi and 100% sRGB color accuracy. The Dynamic Light Control feature automatically adjusts the white point of the display depending on the ambient light of the surroundings.

Impressively, the new Fire HDX is 20% lighter than the iPad Air and weighs in only 13.2 ounces. The frame of the tablet has been made from a single piece of machined magnesium “with a blend of glass and nylon molded onto the unibody.”

Amazon says that the new Fire HDX can last up to 12 hours of browsing the web, and can last for weeks in standby thanks to Smart Suspend, which automatically turns off the wireless connections when the tablet is not in use.

Other notable features of the new Fire HDX tablet includes support for Wi-Fi ac, support for Dolby Atmos and an 8MP camera at the rear. The tablet runs on Amazon’s Fire OS 4 “Sangria”, which comes with a number of new features including Profiles, Family Library, Firefly and ASAP.

Amazon also unveiled an extremely Fire Keyboard with the Fire HDX that comes with its own trackpad, and a bunch of new cases.

The Kindle Fire HDX is already up for pre-order for $379 and will start shipping from October this year.
