At the same time that Apple released its new iPad products in mid-October this year, it also brought the third-generation Apple TV 4K, which was replaced with a new A15 Bionic processor. The capacity doubled and the price was lower. However, it was recently discovered that there was a problem with the tvOS 16.1 system. Making half of the capacity of the 128GB version of the third-generation Apple TV 4K unusable, there are also some small mysteries in the specifications of the processor.
Foreign media FlatpanelsHD recently conducted an actual measurement of the third-generation Apple TV 4K and found that they have a 128GB version of the third-generation Apple TV 4K. After the storage space reaches 64GB, the system will display a full capacity prompt, and it is not allowed. The user continues to install the program, and it appears that tvOS is mistaking the 128GB version of the device for the 64GB version, but even the latest tvOS 16.2 beta has this problem.
In addition, FlatpanelsHD also mentioned that it uses the same A15 Bionic processor as the iPhone 14, but the third-generation Apple TV 4K has one less core on the CPU. Even so, the third-generation Apple TV 4K still brings an improvement over the previous generation. 40% performance score and less processor throttling, the performance is more stable than the previous generation with A12.
