Template:mpu A11 Bionic is a 64-bit hexa-core ARM performance mobile system on a chip introduced by Apple in late 2017 as a successor to the A10.
Overview
Introduced during a keynote event on September 12 2017, the A11 Bionic features six 64-bit CPU cores. The A11 consists of two high-performance big cores which are said to be 25% faster than the A10 and four high-efficiency little cores said to be 70% faster than A10. The chip features Apple's 2nd generation "performance controller" that allows the system to use all six cores at once and is said to offer up to 70% performance improvement in multi-threaded workloads.
In prior models, Apple was using PowerVR GPUs designed by Imagination Technologies. The A11 is the first chip to make use of Apple's in-house designed GPU. The GPU is a tri-core design which is said to deliver 30% higher performance while using half the power as the A10. The GPU has been optimized to for 3D visuals and is optimized around Apple's own Metal 2 hardware-accelerated graphics API.
