The tablet, available in 7-inch and 8.9-inch models, features an IPS display with a 1920x1200 resolution capable of hosting images in 254 ppi.
Amazon's Kindle Fire HD is the first tablet to support MIMO technology for improved Wi-Fi connectivity. The devices has two antennas on board for 41% faster connection speeds than Apple's third-generation iPad, according to Amazon.
The slate is powered by an OMAP 4 processor, which the online retailer claims is comparable to an Nvidia Tegra 3 chip, for increased power and memory bandwidth.
Other hardware features include a laminated display for better contrast and anti-glare support, and a built-in Dolby Digital Plus speaker for improved sound, as well as bluetooth, HDMI and a front-facing camera.
Over on the software side, the WhisperSync service has been expanded to audio books and games, allowing users to pick up their media where they left across different devices.
A innovative feature dubbed Immersion Reading combines the e-book and audio book experience, enabling users to have chapters of the book they are reading dictated to them on command.
The X-Ray for Movies service, powered by IMDB, serves users additive content about films that they have downloaded onto their Kindle Fire HD.
