This page contains information of the FreeBSD port to AMD's AMD64 and Intel EM64T (Extended Memory 64-bit Technology) architecture. The AMD64 architecture was previously known as x86-64 or ``Hammer,'' and the Intel EM64T architecture was previously known as 64-bit extension technology or IA-32e.

The AMD Opteron™ and AMD Athlon™ 64 processors use the AMD64 architecture.

Status:

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.
