I measured the Gflops/W and the big cores give 2.5 which compared to f.ex. raspberry 4 at 2 is not revolutionary.
What gives the M1 an edge is also it's weakest point: proprietary designs, it cannot run things like Unity or Java Minecraft that require generic x86 CISC to run well.
From my perspective the only hope apple has is linux reverse engineering the GPU to allow OpenGL.
