The + AMD64 architecture was previously known as x86-64 or ``Hammer''. + The Intel 64 architecture was previously known as Yamhill, + Clackamas Technology (CT), IA-32e, and EM64T (Extended Memory 64-bit + Technology).The AMD Opteron™, AMD Athlon™ 64, AMD Turion™ 64 and newer AMD Sempron™ processors use the AMD64 architecture.
+The Intel vPro™, Intel Celeron D (some models since ``Prescott''), + Intel Centrino® Duo, Intel Centrino® Pro, + Intel Viiv™, Intel Core™2 Extreme, Intel Core™2 Quad, + Intel Core™2 Duo, Intel Xeon (3000-sequence, 5000-sequence, and + 7000-sequence) processors use the Intel®64 architecture.
+Currently FreeBSD/amd64 runs in 64-bit multiuser mode, in both Uniprocessor and Multiprocessor mode.
The AMD64 platform is currently a Tier 1 FreeBSD platform.
