What’s interesting to me is how big the steps in process node sizes are. I thought the 5nm to 3nm step was huge—it’s a 40% reduction! And 3nm to 2nm is similar—a 33% reduction. But then I looked at wikipedia’s list of process node sizes and, well, they’ve all been 30% to 50% over more than five decades. Which is of course Moore’s law, but I figured there would be more, smaller steps.
