Intel would have called N4 a + node, since it's a tweak to TSMC's existing n5 node. They don't put a hard number on power savings, but they have said it's a 6% die shrink. Apple also targeted performance per watt last year without a node change. >In our extensive testing, we’re elated to see that it was actually mostly an efficiency focus this year, with the new performance cores showcasing adequate performance improvements, while at the same time reducing power consumption, as well as significantly improving energy efficiency. https://www.anandtech.com/show/16983/the-apple-a15-soc-performance-review-faster-more-efficient/4 https://www.anandtech.com/show/16983/the-apple-a15-soc-perfo...
