There is a huge difference. According to your logic Shredder 8 has about 2818 ELO Fide on A1200. Now we assume (simplifying) 50 ELO gain for doubling the clock speed. So Shredder 8 has about 2968 ELO Fide on a Quad Opteron. You get the point? Btw,a Palm T3 400Mhz is close in speed to a Pentium 100 for Chess. Hashtables at a Palm are also not nearly the 80MB used by SSDF for 128MB machines. Michael > >Bruce Humphrey
