I have a laptop that has a 64 bit processor, but it has a 32 bit vs of vista. What would change if I added a 64 bit version of vista? Also if I leave it at 32 bit version of vista is there any benefits?


I mean I don't see what the big deal is? Can some one please point out the prospects?

On the desktop side, you don't have much advantages now. Because like when we passed from 16 to 32 bits, an application has to be developed to use those functionality.

The most noticeable difference will be the max RAM available to a system.
A 32 bits system is limited to a bit less than 4GO. Put more in the computer, and it won't be used.
Because you are limited to 8^32 bits of addressable memory addresses.

What will change too is that the amount of information that can be computed simultaneously will increase. Basically, you double the width of your processing pipes, so theoretically, 2 times more datas will be able to be processed in 1 CPU cycle.

Here is a fairly good writeup about to 64 bits:

most of the software built on 32 bit so if u upgrade to 64 bit OS you can not see major performance gain...

Yes I am agree with Tripy... but its true that most of the application softwares are still 32 bit in nature

In fact a lot of 32-bit software won't even work on a 64-bit os.

But the difference is definitely noticeable if you do have a needed 64-bit application that can take advantage of it. The last 16-bit operating system was Windows 3.11. So the difference from 32-bit to 64-bit is like the difference between Windows 3.1 (16-bit) and Windows 95 (32-bit). Huge.

More registers.

I've been using both XP and Vista 64-bit for 6 months now and I have had no problems with it. No software conflicts as of yet. Many people where telling me I would run into issues as well. The main advantage is being able to use more than 3GB of ram. It can help a lot in apps that eat up a lot of ram or if you like to multi task. I love my 4GB of ram personally. I just go through everything on my computer w/ ease.

Take the 64 bit processor, there is no need to delve into the old times, many programs support 64bit, I program 64bit
