For a base consumer model, this new 2020 M1 based Mac mini appears to totally crush the previous low-end i3 intel in almost every way (except for not being able to upgrade the ram later) - it should have CPU performance near the i7 model, and GPU performance around that of adding a Radeon 560 eGPU (maybe a little better) to the previous Mac mini, so in that market, it is very good and I will easily recommend it to some users.
It's just on the high-end comparing to what was possible on the previous i5/i7 2018 Mac mini with upgradable and how much ram it could take, number of screens, eGPU options, 10 Gb Ethernet option that it is lacking. At least the previous model is still available until some future M2/M3/etc... are able to get it back into that range hopefully.
