Hardware
Both the 7 inch and 8.9 inch LCD models contain a Qualcomm Snapdragon 800 processor that has an Adreno 330 GPU. The models also have a 1.2 megapixel front camera that shoots 720p HD video. The 8.9 inch model has an 8 megapixel rear camera that shoots HD 1080p video. The exterior surface has angular, raised plastic edges with the power and volume buttons located on the backside. The Fire HDX features Dolby Digital Plus audio engine powering the two attached speakers. A normal user will get about 12 hours of battery life from a full charge.
The Fire HDX 8.9" refresh in 2014 uses a Qualcomm Snapdragon 805 processor with an Adreno 420 GPU. The sound system features Dolby Atmos speaker technology and the Wi-Fi version weighs 13.2 ounces (375 grams).
Software
Both models use Fire OS 3 which is a proprietary fork of Android 4.2.2. It features "Mayday", a button for free tech support available any time, "Silk", a cloud-accelerated browser, the Amazon Appstore for games and apps and Amazon.com services for media content purchases. The tablets can send video content to a supported TV, game console or through a device like a Wireless Display HDMI adapter wirelessly using "Second Screen", but cannot send content via a HDMI cable like its predecessor, the Kindle Fire HD.
The 2014 refresh uses Fire OS 4 "Sangria", which features profiles so each user on the tablet can have their own settings and apps.
Mayday feature
Sascha Segan of PC Magazine mentioned: "Press the Mayday button, and within 15 seconds, a live Amazon operator appears in a video chat window on your screen to answer all of your Kindle Fire questions. He or she will even tell you what apps to download. I've never seen anything else like it on a tablet." In his review of the Kindle Fire HDX 7" he called the Mayday remote video support feature as "revolutionary" and "Amazon's most exciting feature".
Fire OS UI
The Fire HDX's UI has a "Carousel" which contains the most recent apps used and ones that have been updated or purchased recently. The Carousel also holds documents, videos, music, and books. The Fire HDX also has a favorites tab in which the user can access the users apps from any other application.

Reception
Engadget gave the Fire HDX an 85 out of 100, saying that it may be the most compelling case for Amazon's tablet ecosystem. While advanced users may be turned off by the limited app selection, the display's gorgeous color accuracy may make the tablet a good buy for everyone else, especially Amazon Prime members.
PC Magazine gave the Amazon Kindle Fire HDX 7" (Wi-Fi) edition 4 out of 5 and rated "Excellent" while following pros were noted: "Sharp screen. Fast processor. Extremely easy to use. Amazing live tech support."
The Fire HDX's screen has high color accuracy and high pixel density at 339 PPI, and as of early 2013 was one of the highest of tablet devices commercially available. However, CNET pointed out that no Google Play access means limited app selection compared to other Android tablets and some users may be bothered by an additional $15 to remove ads on the lock screen, while ads on the home screen can be removed with a system setting.
The Fire HDX supports local FLAC and Wav music files up to 24/96 using Fire software and Apps like Avia (which also supports 24/192). Using music streaming Apps such as Mezzmo and Avia the Fire HDX supports UPnP/DLNA servers for FLAC and Wav playback (up to 24/192) for local and remote device playback.
