Safari (original) uses ~300-400MB with 20-100 tabs open. I think they use a different way of storing tabs which are not on your screen at that moment.
(I didn't check Safari (original) for nothing-open-and-idle RAM usage, simply because I didn't want to have to reload all my tabs, so I booted Safari (Technology Preview) to quickly test it.)
