It supports videos up to 1080p and 60 fps. Launched in 2015, the Apple TV HD uses the A8 chip with 64-bit architecture. SpecsĬurrently, Apple sells the fourth and sixth generation of its set-top box. With a similar design to its predecessor, the main change is the A12 chip and the second-generation Siri Remote.

The sixth-generation Apple TV, or the second-generation Apple TV 4K, was introduced in April of 2021. This model is similar to the fourth-generation model with the only difference being the addition of vents on the base and the removal of the USB-C port. Two years later, in September of 2017, Apple introduced the fifth-generation Apple TV, or the Apple TV 4K, which supports 2160p output, HDR10, Dolby Vision, Dolby Atmos, and includes the A10X Fusion processor. This device includes the A8 processor and support for Dolby Digital Plus. With a brand-new black remote charged via Lightning cable, it introduced the tvOS operating system with an App Store allowing downloads of third-party apps for video, audio, games, and other content. The fourth generation, or the Apple TV HD, was the biggest revamp to the set-top box in years, and it launched in September 2015.

As of 2021, the third-generation set-top box still works with streaming services including Apple TV+, Apple TV Channels, Amazon Prime Video, and Netflix. It included the A5 chip and support for 1080p output. The third-generation Apple TV was released almost two years later in March 2012.

It also supported output up to 720p over HDMI only. Also different from the first set-top box, this one was only used for streaming content. The HDD was replaced by 8GB of internal flash storage, enough for buffering purposes.

In a smaller, all-black case, it was one-quarter the size of the original Apple TV. The second-generation Apple TV was announced in September of 2010 and was the first model to run on a variant of iOS. Shipped six months later, the first Apple TV had a 40GB HDD, and a 160GB HDD option was later released.
