The A11 Bionic – yes, that’s its real name – is a 64-bit, 6-core processor (two performance cores, and four high-efficiency cores) that Apple claims is the “most powerful and smartest chip ever in a smartphone.”

It features 4.3 billion transistors and its two performance cores are 25 percent faster than the A10 chip, and the four high-efficiency cores are 70 percent faster the A10. It also features Apples second-generation performance controller that is 70 percent faster for handling multithread workloads than the current controller.

The A11 Bionic also features the first Apple-designed GPU that is 30 percent faster than the A10 and can offer the same performance as the A10’s GPU at half the power consumption.

Apple has optimized the processor for 3D gaming and Apple’s Metal 2 platform, and is also optimized for machine learning using Apple’s CoreML platform.

The chip also features camera-related improvements, including an Apple-designed ISP (Image Signal Processor) that brings with it an improved pixel processor, faster low-light autofocus, and hardware multiband image noise reduction.

The ISP is leveraged to allow the Camera app to handle real-time Portrait lighting effects

On the video front, the A11 Bionic includes an Apple-designed video encoder, the ability to handle faster frame rates, and real-time image and motion analysis.

Specifically for the iPhone X, the A11 Bionic protects the Face ID data used to unlock the device in the Secure Enclave, as well as handling all the image processing of the face data on the iPhone X using a dual-core Neural engine that can handle 600 billion operations per second, with no data sent to Apple for processing.
