Are 3nm or 4nm chips better than 5nm chips? Does size really matter?

Does a 0.0000004% make a difference that you can notice?

Again, it doesn't work like that in real life, so the "other advancements" bit makes more of a difference when it comes to new chips being more efficient than the previous models. As with any industry, chip makers like to toot their own horn about the process node size they have developed, but these numbers are mostly used because we can understand that 4nm is better than 6nm without knowing all of the details. If chip makers only focused on building smaller transistors and circuits, they would spend billions to offer products that are no better than previous generations.
