Running iPhone and iPad apps natively is no surprise as the hardware is basically the same. However, the lack of a touch screen doesn't make a very good case for the usability.

The M1 is an excellent chip, though it falls short of Apple's tall claims even in carefully chosen workloads.

What I hate is that Apple has locked out of measuring the clock speeds, power usage and temperatures. Hope that it is made available in future updates.

Battery life seems to have improved over the previous generations, though not up to the claims unless tested under ideal conditions.

Things get interesting on the GPU side too. The GPU performs dangerously close the GTX 1050, which is very impressive considering the low CPU+GPU power envelope.

Having said that, the M1 is a very efficient and powerful chip. I'll be happy to see the M1 benchmarked with a standard test suite after a few months when the platform is more mature with more native programs/benchmarks.

But here we are. Extrapolating the data available, it can be inferred that the 4th generation AMD Ryzen U chips can perform around 1.2-1.5x (with a few outliers) of the M1 while still within the 15W limit.
