Dann, An amateur's question: Is the CPU speed doubling theory related in any way to kn/s doubling estimates for ELO gain? Example: Opponent: Toga II 1.0; 17.2 ply; 879 kn/s; Authentic AMD 2177 mhz (1 thread) Me: Shredder 7.04; 13.6 ply; 198 kn/s; 996 mhz; Authentic Intel PIII As you can see Toga is more than 4 times my kn/s but only 2.2 times my speed on mhz. I understand that AMD XP architecture is perhaps not a proper comparison to and older Intel PIII architecture. Is the theory still valid in this case? DHM
