and other places, most visible their product placement:

                                        Basic/Standard/Premium Editions
Red Hat Enterprise Linux AS  	   	   	   	
    Intel x86                                   $1499 	$2499 	 

    Intel Itanium2 and EM64T, AMD64,
    IBM iSeries & pSeries                       $1992 	$2988 	 

    IBM zSeries & s/390*                        $15000*	$18000*

Red Hat Enterprise Linux WS  	   	   	   	
    Intel x86                          	$179 	$299  	 

    Intel Itanium2 and EM64T, AMD64  	$792

RH had the support for x86_64 running before amd64 was called amd64
and as the kernel and GNU did they didn't change it. But the customer
visible name is amd64.

The visible product name for Debian is what the arch is called and
that should be amd64. That we also have that name as file 'extension'
in the debs instead of the old/gnu name x86_64 as rpm does shouldn't
stop us.

Same story I believe.

(New) Users will only see the sticker on the cpu and Linux Box. And
all distributions use Amd64 or for Amd Althon(tm) 64.

The developers chose x86_64 before it was named amd64 and they never
changed it. For technical reasons we can't use x86_64 without breaking
a lot of assumpions in tools.

Having x86-64 causes problem with the - for some sources and will be
very confusing when both x86_64 (the gnu name) and x86-64 (the debian
name) appear in e.g. the debian/rules file.

ifeq ($ARCH,x86-64)
     ./configure --host x86_64-linux -DWITH_BIG_INTS ....

Having the two clearly distinct (amd64/x86_64) helps spotting which
one is ment and gives clear errors if the wrong one was used.
