I don’t know which things here are actually relevant to the differences between the two, but of course there have been changes. Core counts are much higher. You can stripe some enterprise SSDs and get bandwidth within an order of magnitude or so of your RAM. Yet clocks aren’t that much higher, and user-supervisor transitions are comparatively much more expensive. There’s a reason Lemire’s talk on simdjson is called “Data engineering at the speed of your disk”.
