I was under the impression this was the current definitive list as the Windows 11 page says "1 gigahertz (GHz) or faster with 2 or more cores on a compatible 64-bit processor or System on a Chip (SoC)" so I took it as non-negotiable to need one on this list.
Edit: I just realized, what if the health check tool is simply cross-checking people's chips with this list? Maybe that's why so many people are getting this problem.
