This dismantling is the refurbished iPhone 8plus internal configuration of the iusedphone, which is consistent with the original iPhone 8 Plus, and the Intel baseband version of the iPhone 8 Plus A1897.
The iPhone 8 Plus A1897 is proven to be powered by the A11 Bionic AP, labeled TMHS09, in a stacked package (PoP) with LPDDR4 SDRAM running memory from Micron, model MT53D384M64D4NY, capacity The size is 3GB. The actual measurement results show that the size of the A11 chip is 89.23 square millimeters, which is 30% smaller than that of the A10.
The biggest feature of the A11 biomimetic chip is the built-in dedicated "Neural Engine". The neural network engine is currently capable of many tasks, including smarter identification of people, places and objects, as "face ID" and Innovative features such as “moving expressions” provide powerful performance and are used to improve Siri and AR applications and more.
