is there a performance increase in going from 32 bit to 64 bit versions of windows? i mean in windows..

[zanejohnson]

is windows snappier, or has anyone noticed a performance increase going from say xp32 to xp64?

going to frys in the next few days to exchange a defective vid card and was debating picking up a copy of vista home premium 64 bit....

The difference from Xp to Vista will be far greater than from 32bit to 64bit. I'd say the capability to utilize the full 4GB or more makes 64bit have a slight edge in 'performance'. I dunno...I am really happy with my 6GB/Q6700 64bit Vista Home Premium system. Runs like a dream, stock.

that's not what im asking, im asking if the extra data per cpu cycle is gonna make a noticeable increase in speed, and/or the snappiness of windows...

i mean theoretically it should right?

Oh....AFAIK, no.

there probably is, but it's imperceptible

Wrong forum. How was the 60 days in jail?

Not much at all. As a percentage of operations, how often do you think that the OS itself needs 64 bit numbers to do its job? That's all a 64 bit CPU will speed up, all other factors aside.

The only way the extra bits make a difference is if the original data was greater than 32 bits and had to be broken up to fit in 32 bits. Example: 64 bit addition on 32 bit prcoessor, you can't do it natively, but you can set up the code to do it any way. If you move to a 64 bit processor, it does it in one native operation instead of multiple operations. You can't think of 64 bit processors as doing 2 32 bit operations, but rather able to process large data sets(greater 32 bits) in a single operation.

IF you build a great rig like me, you'll want only the best. That includes Vista Ultimate 64.

And Ubuntu.

And OSX.

Triple boot baby!

i went from xp 32 to vista 64 and it seems like my programs launch much faster than before. i don't know if its because i can use the full 4gb of ram now or what. I don't have any hard proof that it is faster, but ti seems faster to me.

Stop it. Just stop it.
