On my Tungsten T (with a 144 MHz processor), the "Speed index" (found in the "Options" menu) reports a TigerMark of 0.73. From what I have heard, this is slightly slower than a 33 MHz Dragonball processor. Of course, the ARM will blow the Dragonball away completely when Christophe finally finishes his ARM-native version. >e.g. you could post a position and how long it takes that tiger15 >(with a hash of 1024 KB) reaches ply 10 or whatever... Feel free to suggest a position if you want, and I'll let Chess Tiger and Chess Genius analyze them on my Tungsten T. I'm not sure there is much point, though. If you just want to run the 68k versions of the engines, the ARM Palms are not that good, and you can just as well get yourself a high-end 68k unit. So far, the only ARM-native engine available is Chess Genius. It doesn't make much sense to compare the speed of the ARM engine to the 68k engine in the case of Chess Genius, because they are two entirely different versions of the engine. The 68k version is the old Mephisto Roma, while the ARM version is comparable to Lang's latest PC versions. I find the ARM-native Chess Genius to be extremely impressive. It searches around 25,000 nodes per second on my Tungsten T. I guesstimate that the difference in playing strength compared to Tiger is at least 150 Elo points. >then i could try this with my Palm M100 and later with other palms >i would like to buy. > >I don't know so far which palm to buy: > >Palm zire 21 > zire 71 >Tungsten E >or Sony soandso. These are all roughly the same from a performance point of view, I think. The processor speeds are not that different. Tord
