How fast can a Raspberry pi change its Gpio Pins per second? (lemmy.ml)

Im currently making a costum 10x10 led matrix, and for it to be able to display senseable stuff, im trying to segment the display into 10 vertical lines which cycle at at least 100hz. Would a Python script on a raspberry pi be able to cycle its GPIO pins at this speed? Or Would an arduino or other Microcontroller be able to do it better?

There is a lot of pseudoscience around human vision and frequencies, so I'd take that with a grain of salt. 100hz isnt that fast as far as microcontrollers go, so you should be able to reach that target. Good luck!
