Maybe, but what scenarios are there where you'd want that, be willing to spend 30 dollars on your microcontroller solution and not benefit from a more capable linux SOC? (With an optional $3 M0/M3 for realtime if required)
Yes, it's not needed for every use case. There are some obvious places where 600MHz helps, either for input sample rate or output waveform. The Teensy 4.0 is $20, with the same processor as the 4.1.
Also, 100 mA current draw with the CPU at full speed. For some use cases, that is helpful...versus the RPi.
