Just for giggles I did a quick test. Since we have a 16" Intel MBP and a 13" M1 MBP right next to each other, and since both have Logic Pro installed, I took the Billie Eilish track that's on there and exported it out as an AIFF at 96 kHz and 24-bit. I set both machines to start at the same time. Both machines are very quick, but the M1 was nearly twice as fast, as near as I can tell. This was not a "controlled" experiment, but it was good enough to make the point.
Granted, this is not a GPU test. There aren't any apps on the demo machines that will give me an option to test that.
