The Fire TV offers HDMI and optical audio, with support for Dolby Digital Plus and 7.1 surround sound pass-through, along with an Ethernet port and a USB 2.0 port. According to Amazon, the Fire TV is designed to outpace competitors like the Apple TV and Roku in performance: The 0.7-inch-thick box features a 1.7 GHz quad-core CPU, 2 GB of RAM and 8 GB of internal storage, along with a dual-band wireless radio for 1080p streaming over 802.11a/b/g/n Wi-Fi. The company said that it does not intend the Fire TV to compete with gaming consoles; instead, its gaming capabilities are geared toward people who don't already own a console but may play games on a smartphone or tablet. It has a dedicated controller accessory.
The device runs "Mojito," version 3.0 of the Android-based Fire OS which is compatible with Android Jelly Bean version number 4.2.2. According to Amazon, that will make it "simple for developers to port their services and games over to Fire TV."
Dan Seifert from The Verge reviewed Fire TV on April 4, 2014, giving it an 8.8/10 and largely praising its current functionality and future potential. Dave Smith from ReadWrite wrote: "Fire TV aims to be the cure for what ails TV set-top boxes. Sadly, the Amazon box leaves much to be desired." GeekWire editor Andy Liu's review is headlined "Amazon's Fire TV sets a new bar for streaming boxes."Ars Technica praised the device specs that are better than the competition, the build quality was high, and if you use Amazon content, the microphone works very well. However, the reviewer did not like that media browsing puts Amazon content in the front thus making other apps less convenient, the game selection is limited and many games are unoptimized, and its free space is only 5.16GB, limiting the amount of games that can be installed.
