Is motion capture better on A13 (Third‑generation Neural Engine)?

I've been playing around with Montion Capture in ARKit 3. The motion capture requires an A12 chip or above. Can anyone tell me if the capturing works better on the A13 chipset versus A12? And by working better I don't mean just faster, but actually recognizing more movements/postures. If so I will go a get an iPhone 11.
