True, but those are really annoying to program and are mostly meant for hard real-time rather than maximum speed.
The speed on the BBB for GPIO's is okay (I can get to about 12.5MHz with some care). It's more annoying that you actually have to be in supervisor mode to change the I/O direction of a GPIO pin.
