If you want cpu information in verbose (!!!) form, look up the CentOS
archives from 1-3 months back. There's a guy named Bryan J Smith who
waxes eloquent for pages and pages on every imaginable topic, but he
covered a lot of the basics about recent cpus and memory management.
What little I remember, AMD has two 64-bit lines, one of them for
consumers with normal memory chips, and one for commercial use
supporting only ECC registered chips. The Pentium 64-bit stuff is not
as good, due to lack of internal paths, but that's about all I
remember.
