Many Faces of go is currently much slower. On 9x9 it does about 18k playouts per second, on two CPU cores, so about 9K per thread. The average 9x9 game is about 92 moves, so there are about 1.6 million board-settings per second.
The playouts are far from random. Many moves are local responses to the last move, and when there is no forced local response, the global moves are not fully random either. My original light code did about 55K playouts per second on one CPU core, but was far weaker.
