Yeah the first iPad pro is where Apple started to close the gap... by the way that article you quoted brings back memories... I am a regular reader of Anandtech and I wrote a huge comment underneath this article back then... (someone even called it a "wall of text"... ?)Exactly. M1's nothing special on iPads. Just natural progression coming from the A12X/Z.
We've had excellent battery life, thermals and silence ever since the original iPad. Performance? A8X was a turning point and A9X is when they started closing the gap with current gen mobile Intel.
