Federighi stated that the A12z in the test units show what Apple can do when they're not even trying. "And they're going to be trying."

So let's define "performance". Are we talking geek-bench scores or real-world processing?

If benchmarks, the A12z already performs better than Intel low-end and mid-range chips. And that's in a tablet throttled to minimize temp and maximize battery life. What happens when they have a notebook's power and thermal budget?

Not to mention that the A12z is about two generations behind, process-wise.

If real-world processing, I can point you to videos where people are doing 4K video editing and real-time rendering on iPads and the silly things aren't even breaking a sweat. All of the custom silicon for image processing, video processing GPU performance, AI processing...

Sorry. but I think there those chips are going to fly.
