Maybe it's oversimplifying, but is is there any valid comparison to make from a conceptual standpoint? One of the distinguishing features people have highlighted with the M1 is a 128-bit wide bus, much as the Sony/Toshiba Emotion Engine has (though it appears to have 128-bit wide registers, while the M1's are 64 bits wide), as well as custom supporting hardware (the M1's Neural Engine and image signal processor, as opposed to the EE's two vector processing units and hardware MPEG-2 decoder). Can someone who understands more about processor hardware provide some input?
