If it comes to performance alone, there is no doubt that M1 is stronger, M1 has more powerful single core, multi-core and GPU performance. In fact, the small nuclear Icestorm of the A14 family has also been greatly improved, and the small nuclear IPC of the A13 alone has been improved by about 30%.
On the GPU side, M1 is also the same as A14, but the scale is much larger than A14, A14 is a four-core GPU, M1's GPU has eight cores.
