Apple is updating the iPod touch with an A10 Fusion system-on-a-chip. Other than that, it looks pretty much like the old iPod touch with a 4-inch display, a classic home button and many different color options.

The A10 Fusion chip was first introduced with the iPhone 7. In other words, the new iPod touch performs more or less just like an iPhone 7. Just like the previous version of the iPod touch, it supports iOS 12. But you can now launch ARKit apps and start group FaceTime conversations — the A8 wasn’t powerful enough for those features.
