In the {{\\|A10}} Apple had two pairs of cores - two little and two big, with little cores operated at half the frequency of their big cores counterparts. A11 doubles the number of little cores. It's worth pointing out that in the A10 at any given time only a single pair was active. In the A11, with the introduction of Apple's 2nd generation "performance controller", this restriction has been removed. The system can now 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 {{imgtec|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 that is said to deliver 30% higher performance while using half the power as the {{\\|A10}}. The GPU has been optimized for 3D visuals specifically for gaming apps and is optimized around Apple's {{apple|Metal|Metal 2}} hardware-accelerated graphics [[API]]. | In prior models, Apple was using {{imgtec|PowerVR}} GPUs designed by [[Imagination Technologies]].
