Amazon Fire TV Stick (3rd Gen) and Fire TV Stick Lite are official as the two new variants in its popular range of streaming devices. The new Fire TV Stick variants support streaming at up to full-HD resolution, and run on a redesigned user interface of Amazon’s Fire TV OS, which will roll out later this year starting with the new devices. Announced close to four years after the release of the dated Amazon Fire TV Stick (2nd Gen), the new Fire TV Stick devices go on sale in India on October 15, and are already available for pre-orders.Amazon Fire TV Stick (3rd Gen) specifications and featuresThe core design of the Rs. 3,999 Fire TV Stick (3rd Gen) isn’t changed, with the streaming device connecting to a television or monitor using the HDMI port, and drawing power through an included wall adapter that is plugged into a power outlet. Also included is the remote; for the Fire TV Stick (3rd Gen), the remote is also capable of controlling most televisions for power and volume, apart from standard controls for the user interface.The key differences are under the hood, with a new 1.7GHz quad-core processor that is claimed to be 50 percent more powerful than the Fire TV Stick (2nd Gen), and a redesigned user interface for Fire TV OS that includes user profiles, improved search and content discovery, and access to Amazon’s Alexa voice assistant. There is 8GB of internal storage for apps and app data.Streaming at up to full-HD (1920×1080 pixels) resolution is supported, and interestingly, Amazon states that HDR streaming at up to the HDR10+ format is also available. While it isn’t clear how this will work since HDR requires 4K at the hardware level, support for the format at the software level is an interesting touch. Dolby Atmos Audio is also supported on the Fire TV Stick (3rd Gen).Amazon Fire TV Stick Lite specifications and featuresThe second of the key launches in the range is the Amazon Fire TV Stick Lite. Priced at Rs. 2,999, it looks identical to the Fire TV Stick (3rd Gen), and has similar specifications and features.
