 µCNC with a configuration similar to Grbl is be able to keep up to 30KHz step rate for a 3 axis machine on an Arduino Uno at 16Mhz. (the stated rate depends on the length of the segments too, since many short length segments don't allow full speed to be achieved). For this specific type of use (like in laser engraving) a 16-bit version of stepping algorithm is possible pushing the theoretical step rate limit to 40KHz on a single UNO board.
