Amazon today introduced a new Fire TV with HDR and 4K capabilities, which marks the first time the device has offered the higher-resolution video. The redesigned device, which resembles a small, square hockey puck, can display 2160p video at 60 frames per second. The device has Dolby Atmos integration and comes with an Alexa voice remote.

The new Fire TV is powered by a 1.5Ghz quad-core processor. It has access to thousands of apps and Alexa skills, and more than 500,000 TV episodes and movies, the company said. The device will go on sale for $69 and is available for preorder now. It will come out later this year. You can also buy a bundled Fire TV and Echo Dot for $80, or a Fire TV Stick and Echo Dot for $60.
