This depends entirely on your usage case.

As part of my job I take 3D scans of objects and reproduce them digitally.

There are many ways of doing this, the most popular of which is to use Autodesk Recap and upload hundreds (if not thousands) of DSLR images so it can work its photogrammetry magic, server-side and spit out your model. Don't like the results? Back to taking pictures you go.

If you want to do this offline you still need hundreds-to-thousands of images but also a weekend of processing from your desktop. (My i7, 32gb RAM, RTX work desktop takes at least 24 hours) and again if you don't like the results, back to taking pictures you go.

Via the app Scaniverse (free on the app store) and utilising the LiDAR scanner alongside the 60fps of a video feed an iPad Pro is capable of producing a 1:1 accurate model of something on a few minutes without an internet connection.

To call this game changing for my workflow is an understatement. I could use our professional grade LiDAR scanner which costs £20k and requires specialised software but the fact I can get just-as-good results on an £800 piece of consumer electronics is incredible. The iPad does a lot more than you think!
