It might be the fastest on earth but that is just one side of the coin. The other side is how the software you run can utilise this power & speed.
For years we heard that A* chips where the fastest on each iPad Pro and yet we can’t even get a decent desktop-like experience of iMovie (or any movie production software for that matter). Same with image processing software: we just had a OK version of Adobe Photoshop while the first iPad Pro was released 5 years ago.
What worries me a bit is that most of this ‘super M1 power’ will be used/wasted in Rosetta Intel-M1 translation that would, for the normal user, feel like the same as before ... until of course new M1 software is released. That could take years.
