AMD64 calls for a native implementation of 32-bit x86 instructions.
How they implement 64-bit mode is what sets apart the AMD from the

Yep. You might have some problems with some hardware whether in 32-bit
or 64-bit mode (e.g. NForce 4 chipset).

Opteron is AMD's server chip. Xeon is the Intel counterpart. Both
implement AMD64 (branded as EM64T in Intel's implementation) although
AMD's implementation is far superior due to many reasons you can
Athlon64 and Athlon64 X2 are AMD's consumer chips that implement
AMD64. The Pentium 4 Prescott and Pentium D also implement EM64T; then
again AMD's implementation is again far superior.
