I haven't measured anything, but I would expect closing the tab and 
opening a new one would use less memory... IF there is any difference at 
all.  I believe the issue is retention of previous page information 
which doesn't really change between the two cases.  You don't say which 
browser you are using, but the ones I use retain all manner of info on 
visited pages including a complete image.  At least that is what I've 
read when browser memory usage is explained.  I can't understand why a 
browser uses GB of memory except for that sort of memory use.

I think you can tell the browser to not retain all that info, but don't 
ask me how to do it.  Also this depends on the browser.

I have all but quit using Firefox because it runs so slow.  I use 
Windows and am primarily using Opera and some Chrome these days.  Opera 
seems to be the most well behaved browser I have seen, but every once in 
a while a page won't work correctly with it.  I tried looking at a 
supermarket sale page and had to use Chrome.  But that is *very* 
infrequent.

Every page has a full bit mapped image generated in RAM, so that isn't 
an issue.  But it does have to uncompress the image files (jpg or 
whatever) to bit map.  That uses CPU time.  You may be facing a memory 
shortage.  I run with 16 GB, but I also have bunches of tabs always open.
