Device Specifications: Fire TV (Pendant/Box)

Fire TV (Gen 3) was released in October 2017 and supports resolutions up to 4K ultra HD at 60 fps. It also supports HDR10 (High Dynamic Range, which results in bolder contrast and more vibrant colors) and supports Dolby Atmos for richer sound. Gen 3 has a pendant form factor, making it less visible and more portable (this form contrasts with the set-top box form of the Gen 1 and Gen 2 models). Its 1.5 Ghz quad core processor has more power than the stick, and it has a micro USB port that can optionally accept an Ethernet adapter. Gen 3 also runs Fire OS 6, which is based on Android API level 25.

Fire TV (Gen 2) was released in September 2015 and supports resolutions up to 4K ultra HD. In contrast to the Gen 3 model, the Gen 2 has a set-top box form factor, provides a USB port, has a direct Ethernet port, and runs Fire OS 5. Its fast CPU (2 Ghz and 1.5 Ghz dual cores) gives it strong processing power, and it is compatible with a game controller. The Gen 2 device is now available in stores only as a refurbished device.
