The biggest gains come with number crunching. I'm working with cryptographics hash functions where I need to multiply large numbers together. A 64-bit multiply is able to do 4 times the work of a 32-bit multiply, not to mention the overhead involved with assembling the 32-bit pieces together. This can lead to huge performance gains, but only because it is tailored to such an improvement. Most GUI programs are IO bound and can't really take advantage of 64-bits. -Joe _______________________________________________ arch mailing list [email protected] http://www.archlinux.org/mailman/listinfo/arch
