Please excuse my ignorance, but what exactly does “final beta” mean?
Also, I'm not too familiar with it, so why does it imply that the 64 bit version only works on AMD CPU's? Is there no 64 bit version for Intel?
And those are usually mean old bearded Unix old-timers that will strike down upon thee with great vengeance and [condescending] anger.
And you do not want to upset these people.
Disclaimer I'm a young Unix old-timer, currently growing a beard.

"After launching the architecture under the "x86-64" name, AMD renamed it AMD64 in 2003; Intel initially used the names IA-32e and EM64T before finally settling on Intel 64 for their implementation. x86-64 is still used by many in the industry as a vendor-neutral term, while others, notably Sun Microsystems (now Oracle Corporation) and Microsoft, use x64."
