They’ll be 2-4x faster in some multicore tasks. CPU benchmarks specifically break out single core performance as a separate metric, because as of 2020 a lot of everyday work is single core bound (stuff like 3D graphic design, video editing or compiling large codebases not considered “everyday work”).
Not to mention that even in multicore tasks, you don’t usually scale perfectly linearly due to overhead. And also, the biggest Ryzen processors are usually in desktops, and Apple Silicon hasn’t entered that market yet.
For most everyday work - Raspberry Pi is fast enough, so it's not even an argument. Raspberry Pi 8GB is 10x cheaper? There are mini desktops starting at $250 that will do everyday work.
If you throw in "everyday work" - then we have passed the need for new chips altogether.
That's a bit of an overstatement. Booting from SSD instead of SD card has an enormous uptake in performance. I have yet to hear of a Pi 4 that couldn't overclock to 2GHz which is a pure uplift of 25%. Moving to 64-bit PiOS gives another double-digit jump in performance too. Not record-breaking, but not unusable either.
