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 are custom RTOS like Zephyr which run on pi.

Also Linux has RTOS versions which are pretty decent.
