There are some features that the program can take advantage of even if the 64-bit registers do not help. There are twice as many registers, more cache, and things like branch prediction are probably improved. A program that doesn't use a single 64-bit value can see a decent speed increase from these things. Of course, some might not see any speedup at all. >Strange, one would think that double the speed would increase ELO significantly >more... Some people think that even 35 ELO for a 50% increase would be too much, since it is based on the assumption that doubling the speed results in +70 ELO. Some people think doubling the speed is only about +50 ELO.
