Apple TV 4K is a product launched in June 2018. It is a product line that has not been updated by Apple for more than 2 years. Every year, some people expect that Apple TV 4K will launch an updated version, replaced by a faster processor to cooperate with Apple Arcade game subscription service.
From @Fudge news, Apple plans to replace Apple TV with A12X/Z or even A14X processors, and it will also have its own GamePad with 6GB RAM, which will greatly improve the game performance. In the future, some games will use at least A13 processors to run , To achieve the quality of the game like The Legend of Zelda Wilderness.
Apple Arcade is getting BIG money poured into it. There are currently titles in the works that are aiming to rival the likes of Breath of the Wild, which is why new A12X/Z AppleTV, "A14X-like" AppleTV, and Controller are in the works.— Fudge (@choco_bit) October 3, 2020
Some games will require A13 and up to run 💁🏼♀️
