32-bit machines provide for 4 GB of directly addressable memory. 64-bit
machines increase that to 17,179,869,184 GB. Why do we care and when will it
matter?

4GB is not great when you're processing video, which quickly gobbles up
RAM. It matters already - manufacturers are trying to win control of the
living room.

Software that requires loading of complex models, e.g. speech
recognition is also a voracious RAM user. Throw all of these things
together and you get games, and other other highly interactive
contextual software.
 
The i86 32-bit architecture isn't limited to 4GB. This limitation is only a
design choice in the current generation of Windows. With segmented (as
opposed to flat) addressing mode (akin to the old 8086 style), it can
address up to 64TB (65,536GB) virtual memory. All it would require would be
a recompile with the appropriate parameters, and a couple of modifications
in the kernel's initialization module.

If you're a serious power user, and hungry for RAM, this will be very very
useful :o)
Especially in server environments - how do you think organisations like
Xerox and eBay run? :o)

bill gates claimed that 640k ram is more than enough for any application
ever developed.

That was one if his biggest goof ups... talk about visionaries... lol
 
You may not need a zillion terabytes, but it is how much you get with 64-bit
architecture, it is just math. 4gb is definitely not enough, and 64-bit is
the next logical progression.
 
That his often quoted and also denied by Bill Gates.
No one is able to cite a specific source for that quote from Bill Gates so
it is most likely a myth.
 
LOL he made a statement only recently saying that "I never said such a
thing".... but we all saw the video Bill ;o)

From 1981? When not much of anything was committed to video?

I guess we'll leave it to you to dig up the source since no one else has
managed to in 25 years.
 
Hey Fat Bastard, I'm star struck having a celebrity in our midst! Play us a
tune on yer bagpipes.

What about this whole "virtual layer" between the actual file/folder
structure and the ability to find things quickly using Search boxes and such
in Vista. Don't you think that all that stuff must involve a lot of indexes,
and wouldn't it make sense to try to keep those in RAM for performance
reasons? Do you think there might be a basic "RAM is dirt cheap and
plentiful" philosophy driving that?
 
I would imagine why he would deny it...LOL

but even if he did say it, I can forgive him :-)

Actually yeh, I've been looking back and the video I saw was a Channel 9
one, of him actually saying that what was said was codswallop - and yeh,
there's no actual evidence of it :o)

You're going to have to check facts faster and bite your tongue when you
finally start receiving Microsoft pay-checks. ;-)

Remember, that unlike Bill's supposed remarks, all yours are captured
forever on Google's archives ;-) ;-)
 
Well, there might be that sort of mindset going on, but as far as I know the
indexing is not done in RAM. A nice flat database on the hard disk is still
much much faster than actually searching the drive and that is how it is
done to the best of my knowledge.
