There was a four game match a few years ago where Hikaru Nakamura, #5 in the world at the time, played four games again Stockfish.
For two of the games, Nakamura had access to Rybka which was about 200 rating points weaker than Stockfish. Stockfish won one and the other was a draw.
For the other two games Nakamura did not have Rybka, but had white and pawn odds. Again, one win for Stockfish (b pawn odds) and one draw (h pawn odds).
In all the games, Stockfish was playing without its opening book and its endgame tablebases. It was running on a 3 GHz 8-core Mac Pro.
