I would be interested to compare how Deep Shredder 9 performs on an Apple Quad in comparison to e.g. a Dual Opteron. I know that Opterons are much better for chess than G5s (but I didn't buy this for the chess ...) Using the following test position: [D]8/p5Nk/3B2pp/8/2PP1pn1/4p3/P3P1Bq/R2R1K2 b - - 0 1 the winning move is ... Nf2 The time taken to find that it is obviously winning: (eval > +2 for Black): eMac G4 1.25GHz 73.09 sec Pentium M 1.6GHz 44.58 sec Quad G5 2.5GHzx4 11.26 sec The final bit of output from the engine on the Quad is shown below so that you know which timing I used. I used the bare engines (no GUI) and the uci commands: uci isready position fen 8/p5Nk/3B2pp/8/2PP1pn1/4p3/P3P1Bq/R2R1K2 b - - 0 1 go infinite ========= QUAD info depth 16 seldepth 42 time 8893 score cp 4 lowerbound nodes 20312375 nps 2284085 hashfull 988 pv g4f2 info currmovenumber 4 currmove g4f2 info depth 16 seldepth 42 time 9840 score cp 39 lowerbound nodes 22560861 nps 2292770 hashfull 988 pv g4f2 info currmovenumber 4 currmove g4f2 info depth 16 seldepth 43 time 11266 score cp 202 nodes 26308827 nps 2335241 hashfull 988 pv g4f2 d6f4 h2f4 g7e6 f4h2 d1b1 f2h3 =================
