I mean really, when it comes to instruction processing, many CPU's have supported 64-bit operands and data buses for a long time. Heck, even the Pentium2 can do 64-bit integer operations.
When AMD designed the AMD64 instruction they did try to change some other things in the instruction set like the number of registers. It's these changes that make 64bit programs faster then 32bit program on the AMD64 cpus.
