  <p>This page contains information of the FreeBSD port to <a
      href="http://www.amd.com/">AMD's</a> AMD64 and <a
      href="http://developer.intel.com/technology/intel64/index.htm">Intel&reg;
    64</a> architecture.  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).</p>

  <p>The AMD Opteron&trade;, AMD Athlon&trade; 64, AMD Turion&trade;
    64 and newer AMD Sempron&trade; processors use the AMD64
    architecture.</p>

  <p>The Intel vPro&trade;, Intel Celeron D (some models since ``Prescott''),
    Intel Centrino&reg; Duo, Intel Centrino&reg; Pro,
    Intel Viiv&trade;, Intel Core&trade;2 Extreme, Intel Core&trade;2 Quad,
    Intel Core&trade;2 Duo, Intel Xeon (3000-sequence, 5000-sequence, and
    7000-sequence) processors use the Intel&reg;64 architecture.</p>

  <h3>Status</h3>

  <p>FreeBSD/amd64 runs in 64-bit multiuser mode, in both
    Uniprocessor and Multiprocessor mode.</p>

  <p>The AMD64 platform is currently a <a
      href="&base;/doc/en_US.ISO8859-1/articles/committers-guide/archs.html">Tier
      1</a> FreeBSD platform.</p>
