I just made a test on two machines running gentoo linux. One is a
Pentium4 and the other an Amd64. On the Pentium4, nautilus uses 30,9 MB
and on the AMD64 112,7 MB which is more near four times the memory used
with the Pentium4 than 2.
The same is true for other apps:

			Pentium4	Amd64
gnome-system-monitor	21.5 MB		112.0 MB
gnome-session		17.1 MB		85.7 MB

and so on...

Best regards,
