The processors have changed significantly. I had a OnePlus 3T which I really liked, and recently pulled it out of a box because my daily driver phone broke. The 3T struggled to load modern, bloated apps like Google Maps. The device would chug at most tasks more intensive than scrolling a webpage (and sometimes even then... what a sad state the web is in these days)

By contrast the processor in my work phone (an Iphone) is faster than my laptop.
