The graphics benchmarks are not nearly demanding enough, the framerate on the Galaxy S2 is capped at 60fps, if you look at the Nenamark test the framerate just won't go any higher so the results will be close. It would be like benchmarking 3dmark2001 on a 7800GTX and a 8800GTX with 60fps a framerate cap, it won't tell you much. The only odd result there is smartbench, even my Galaxy S scores higher in that test, but Galaxy S2 wins easily in everything else, the developers need to update that benchmark as somethings not right there.
