iPhone Xs’ A12 Bionic chip features 7nm design, next-gen Neural Engine


In revealing the iPhone Xs on Wednesday, Apple also detailed its core processor, the 7-nanometer A12 Bionic, which includes a new iteration of its “Neural Engine” for tasks related to machine learning, such as Face ID and animoji.

The latest Neural Engine is an eight-core unit, providing “multiprecision” support and a “smart compute system,” Apple said during its press event. Whereas the one in the A11 could handle up to 600 billion operations per second, the new one is capable of 5 trillion.

The heart of the chip is a six-core CPU with two performance cores that are up to 15 percent faster than the A11 while consuming 40 percent less power. Four “efficiency” cores, handling lower-intensity tasks, should consume 50 percent less energy.

A four-core GPU is 50 percent faster, supporting technologies like tessellation, multilayer rendering, and lossless memory compression.

The company is also promising a faster Secure Enclave, used for tasks like Face ID authentication, which when paired with streamlined algorithms should speed up Face ID recognition.
