Another real world comparison. I used Ebsynth (a graphics processing engine that takes frames from a movie and re-renders each one based on one or more 'input frames' with a different visual... to make a short example: you can give it a short movie, then take the first frame and do a painting of it. The software will then be able to produce the whole movie in the 'painted style'. It's rather impressive).
Anyways the same project takes about 3:50 on the 2017 iMac (32GB quad core 4,2GHz i7), and 2:55 on the macbook pro (M1 16Gb). Ebsynth is not optimised for M1 and doesn't use the GPU on either machine.
As usual, the macbook was silent (temps went up to 70 celsius), and the iMac whooshed away like a mini hurricane.
