So far, my Sapphire II has 2.5 - 0.5 against Palm Tiger at 5 minute games. Tiger is overclocked to 28MHz on a Palm IIIe, both have hash tables on, permanent brain disabled. Looks like the Sapphire II is out thinking Palm Tiger by about a ply (3000 nps vs 500 nps). I plan to try some 30 minute games with permanent brain later this week. (This would be easier if Palm Tiger had some sort of serial interface so that I could adapt it to WinBoard like I have my Sapphire II.) >>I think the Sapphire II could act as a kind of basic performance test for Palm >>chess programs, in other words, they should beat it more or less clearly to be >>competitive IMO, in terms of strength (in terms of functionality, the Palm is >>certainly superior). > > >There are not many chess programs which are going to be able to pass the test! >:) Indeed. People forget that the SapphireII is near state of the art at its clock speed (16MHz). Lang's and Morsch's programs in Mephisto units are its only competitors. >>A Pocket PC, or Windows CE program running at 100...200 MHz just must beat the >>Sapphire I think... at least if it is somewhat state of the art. > > >Clearly.

For example, the strongest commercial program for the PocketPC, PalmChess, on a 206MHz iPAQ loses (~35%) against ChessGenius on a 28Mhz overclocked Palm. It would certainly lose against SapphireII which is stronger. Crafty on the iPAQ is stronger than the SapphireII (hash tables help quite a bit.) Ian
