Other than the 20% faster CPU, 4-5 additional hours of battery life, 2e6:1 contrast ratio, and 30% faster FaceID (which might be the difference between the phone seeming to immediately unlock and pausing briefly)?

If Intel or AMD announces a 20% faster chip it would be met with applause. Now imagine if they announced a 20% faster chip that also used 25% less energy. And it also takes great pictures with three different lenses, recognizes your face, has one of the best screens ever made, and so on. If that's not impressive, what would Apple have to do to be impressive?
