No idea on comparative performance, but the AMD64 port of Debian has:
(incl. Intel with EM64T extension)

  http://www.debian.org/ports/amd64/


----

A complete 64bit userland

The AMD64 port is thoroughly 64bit, allowing the user to benefit from
all advantages this architecture has compared to i386:

    * no memory segmentation in low and high memory
    * up to 32TB virtual address space per process (instead of 2GB)
    * 128GB physical memory support instead of 4GB (or 64GB with the PAE
	extension)
    * 16 registers in the CPU instead of 8
    * gcc defaults to sse math instead of 387 fpu
    * gcc omits frame-pointers by default
    * compilation time optimization uses a common base for amd64/em64t
	instead of legacy i386 cruft
    * memory pages are not executable by default

Native execution of legacy 32bit binaries is supported by the kernel,
and core libraries are provided by the ia32-libs package.
