Dear CCC, This posting is dedicated to Thorsten in the first place being the absolute opponent against statistics. He might change opinions after this conclusive posting, Thorsten you will love this one! It's also dedicated to those who still believe that there is no performance increase/decrease when playing on different time controls. (Hi Christophe!) The below data is taken from the latest SSDF list and measures the differences between the used hardware, that is Athlon 1200 Mhz versus the AMD 450, roughly being a factor of 3. 2 Chess Tiger 14.0 CB 256MB Athlon 1200 2714 34 -33 460 63% 2619 +82 13 Chess Tiger 14.0 CB 128MB K6-2 450 MHz 2632 30 -29 585 65% 2526 3 Deep Fritz 256MB Athlon 1200 MHz 2709 34 -33 447 63% 2617 +55 9 Deep Fritz 128MB K6-2 450 MHz 2654 24 -23 901 62% 2568 4 Gambit Tiger 2.0 256MB Athlon 1200 2708 37 -36 381 61% 2626 +67 11 Gambit Tiger 2.0 128MB K6-2 450 MHz 2641 30 -29 592 66% 2522 6 Junior 7.0 256MB Athlon 1200 MHz 2684 34 -33 436 58% 2630 +53 14 Junior 7.0 128MB K6-2 450 MHz 2631 28 -26 717 67% 2505 7 Rebel Century 4.0 256MB Athlon 1200 MHz 2680 36 -35 407 63% 2587 +104 21 Rebel Century 4.0 128MB K6-2 450 MHz 2576 68 -70 105 46% 2606 8 Shredder 5.32 256MB Athlon 1200 MHz 2662 32 -31 498 56% 2619 +56 17 Shredder 5.32 128MB K6-2 450 MHz 2606 31 -30 545 62% 2521 10 Gandalf 4.32h 256MB Athlon 1200 MHz 2649 34 -33 430 54% 2621 +130 32 Gandalf 4.32h 128MB K6-2 450 MHz 2519 36 -36 378 53% 2499 Based on the above comparison the 2004 SSDF list running on 3600 Mhz hardware might looks as follows: 1. Chess Tiger 14.0 CB 256MB Athlon 1200 2714 + 82 = 2796 2. Rebel Century 4.0 256MB Athlon 1200 MHz 2680 + 104 = 2784 3. Gandalf 4.32h 256MB Athlon 1200 MHz 2649 + 130 = 2779 4. Gambit Tiger 2.0 256MB Athlon 1200 2708 + 67 = 2777 5. Deep Fritz 256MB Athlon 1200 MHz 2709 + 55 = 2764 6. Junior 7.0 256MB Athlon 1200 MHz 2684 + 53 = 2737 7. Shredder 5.32 256MB Athlon 1200 MHz 2662 + 56 = 2718 I love this list :) Unknown entries because of no comparison material. 1 Fritz 7.0 256MB Athlon 1200 MHz 2748 38 -35 395 68% 2616 5 Shredder 6.0 256MB Athlon 1200 MHz 2706 37 -36 379 61% 2626 16 Crafty 18.12/CB 256MB Athlon 1200 MHz 2613 33 -32 459 54% 2587 23 Nimzo 8.0 128MB K6-2 450 MHz 2554 24 -24 824 53% 2531 29 Hiarcs 7.32 128MB K6-2 450 MHz 2526 21 -22 1051 48% 2537 34 Chessmaster 8000 128MB K6-2 450 MHz 2517 44 -45 251 45% 2550 A couple of notes: 1) Rebel Century 4 (AMD-450) has played to less games yet (105) to make it a reliable comparison. However the result (+104) doesn't surprise me, Rebel is tuned for longer time controls. 2) It has to be seen if Fritz7 and Shredder6 have not improved playing on faster hardware. Since there is no comparison material yet this remains unknown for the moment. 3) I don't think the above is a scientific conclusion, neither a 100% valid prediction, but IMHO it isn't 100% nonsense also. 4) You are invited to shoot the above into pieces.
