M1 is just a continuation of the same, it’s just fanless, cooler, less energy usage and optimized for a few types of uses (very useful for web). CPUs really haven’t had a jump since sandy/ivy bridge, and GPUs got much better with the nvidia models in 2016, but it didn’t show up in the real world as much as it did in running machine learning algorithms. Gaming laptops existed with good if overly hot and expensive GPUs.
