This is explained in "AMD64 ABI" document on www.amd64.org (also available at www.x86-64.org). Technically, they two different architectures, AMD's AMD64 (formerly known as x86-64) and Intel's EM64T (formerly known as IA-32e). While other x86 vendors call their products "x86 or IA-32 compatible", Intel's EM64T doesn't claim any compatibility to AMD64: "Intel EM64T is an enhancement to Intel IA-32 architecture". Simply searching for "AMD64" on www.intel.com returns nothing. ;) While AMD64 and EM64T seem to be compatible at the moment, can anyone be certain this will hold forever? Neither AMD nor Intel claim any compatibility to each other. Saying only "AMD64 compatible", like David did, would be politically correct (now), recognizing the AMD's lead, while saying "AMD64 and Intel EM64T compatible" would be more technically correct and convenient for our users. Do we care about politics or our users? Mentioning both architectures would also be consistent with our own AMD64 architecture page, http://www.freebsd.org/platforms/amd64.html, and the architecture list on the left of the main web page that says "AMD64/EM64T". I'm for technical correctness, "AMD64 and Intel EM64T compatible". Technically, they are two different architectures, compatible at the moment.
