In this day and age of Electron apps, I would say that RAM matters as much or more than CPU performance but seeing these results competes the story. M1 is good and has the potential to power pro laptops.
I have seen an interesting point raised elsewhere. macOS on ARM will be able to run iOS apps (assuming the author doesn’t opt out). That means that a lot of the uses of electron or similar may no longer be needed. Slack, Spotify, etc. Some of course will still be electron, there’s no native version of VS Code for instance. But it could work out better than expected...
