I have an old Windows mini PC, which is based on a single core Atom CPU. Clicking the Settings button will take multiple seconds to launch the Settings app. I wonder if Windows on the RPi will fare better.
RPi4 has up to 8 GB RAM. I think any RPi with anything better than one 32-bit LPDDR4 memory channel would fare better... at everything. I'd like to see at least a 64 bit wide memory channel if nothing else.
