Apple's new streaming set-top will be called the "Apple TV 4K," and come with a six-core A10X Fusion processor and 3 gigabytes of RAM, according to the latest information gleaned from the iOS 11 GM. [Updated with clarification on cores]
The device will be capable of playing 4K video at 60 frames per second, said the source of previous iOS 11 GM leaks, Steve Troughton-Smith. The A10X is notably the same chip in the used in this year's 10.5- and 12.9-inch iPad Pros, but may lack some of the technologies present in the "A11" expected in the "iPhone X" and "iPhone 8."
On Saturday, code from the GM revealed that a fifth-generation Apple TV will play 2160p video, and as previously hinted, support Dolby Vision and HDR10. For some owners the limiting factor on video quality may be bandwidth, since the device should warn 4K streamers if sustained internet speeds fall below 15 megabits per second.
Aside from upgraded specifications, the set-top will come loaded with tvOS 11, offering features like notification support, automatic light/dark mode switching, and homescreen sync in homes with multiple units. Still more could be revealed at Apple's Tuesday press event, since the company will sometimes keep software changes hidden to protect secrets about hardware.
That event is expected to focus on Apple's new iPhones, as well as an LTE Apple Watch and slightly upgraded AirPods. AppleInsider will cover developments live from the newly-opened Steve Jobs Theater, located at Apple Park.
Update: In a follow-up tweet, Troughton-Smith said that the set-top's A10X will actually have six cores, split in half between apps and background processes.
