Having more than three times as much RAM at twice the bandwidth does help, but not just that; its CPU and GPU are superior too. Not by a whole generation of course, but enough that the results can look noticeably better, as we can see when comparing both the same games on both systems, and also Wii U games to their Switch sequels.
