As usual, this Rene Ritchie explainer is a firehose of information, but really well explained. What I found most interesting is the comparison of the iPhone processors, like the A14, to their Mac counterparts.

As you watch Rene walk through the various Apple Silicon architectures, he lays out the similarities between the iPhone and Mac chips, makes it clear how one begat the other, and how the design evolved from the iPhone’s smaller enclosure to the bigger, higher powered, better cooled Mac.
