Apple has been selling TV boxes for a long time, with occiasional hardware and software refreshes that keep it competitive with similar products from Amazon, Roku, and Google. Today, Apple revealed a new Apple TV designed for 4K playback, with both upgraded hardware and software.

The new Apple TV 4K is powered by the same A12 Bionic chip that powers Apple’s current iPhone lineup, giving the new model “a significant boost in graphics performance, video decoding, and audio processing.” HHDR, high frame rates (Apple didn’t give a specific number), and Dolby Vision video are all supported. Many other streaming boxes already support HDR and Dolby Vision, but Apple also allows an iPhone to function as a color calibration tool, which is definitely unique.
