That's a weird question. What do you have in mind? Generally speaking iOS uses extra resources quite well, leveraging the GPU, image processor, and now AI coprocessor for instance. What are you fishing after? There aren't any Apple employees here leaking company secrets, unfortunately. We only have access to the information that is in the public domain. The phone hasn't been available for independent experimentation or investigation. Since you have access to Apple developer material you should be well aware of this.
