I got my first Intel based x64 servers in late 2004. AMD was 64 bit a
lot longer than that. I'm not sure when x64 on Intel chips became
default on desktop/laptops but it was staggered with Centrino on
laptops for example happening a lot before the cheaper Celeron models.
The 64 bit Centrino chips arrived in mid 2006 for memory. AMD has been
64 bit for a lot longer though.
