Default Vista x86 vs x64

What is the main difference? I know x64 support more ram (or so I have heard) But I am going to be using 4GB. Is there any other differences performancewise? I am going to get the OEM version but don't know which one to get. I am mainly getting it for directx 10 otherwise I would still be using XP.

Im on 64bit vista. Its perfect, makes the best of my 4gig ram too.

Your thinking of 64 bit vs 32 bit processors. x86 refers to a generic and most popular commercial processor architecture; something else entirely really.

As you said in 64-bit windows recognizes 4gb's of ram. However just b/c vista does not officially recognize all the ram, doesn't necessarily mean your computer can't use it. Its more complicated then that.

64-bit is the future of computers. A bit to your processor is a 0 or 1. All the calculations for everything your computer does is translated into a series of 0's and 1's. So if your processor is a 64-bit, that means it can handle a series of 64 0's or 1's in one calculation.

However if you have a 32-bit processor, then to do the same calculation with the 64-bit number it most perform 2 steps instead of 1. Thus slowing it down.

So a 64-bit OS supports the use of 64-bit processing. It's faster, while not by a factor of 2 as one would logically assume since other things come into play too, but it is signifigantly faster. A 64-bit OS can also more effectively address memory, meaning it can make better use of the RAM you do indeed have installed; however this is really more noticeable in servers.

So why would anyone go with 32-bit?

Well 64-bit Operating systems tend to cost more. Not sure on the price difference however, you could look that up. But in order for a program to take advantage of 64-bit processing, it has to be specifically written to do so. And not many programs today are done as such, (probably the majority of the programs you use aren't coded for 64-bit processing). 64-bit OS' are often less stable resulting in more problems. Also the programs written for 64-bit tend to be less stable also. So you have less stability in your OS and your programs.

64-bit benefits are not really seen in things like surfing the web and office applications, as 32-bit is perfectly adequate for this application. However for things that are graphic intensive and require intense scientific calculations, (Photoshop, Games, 3D Rendering, video and music editing, etc.). So if you don't do those things opt for the more stable 32-bit OS. If you do those things rather frequently, opt for the 64-bit if its in your budget.

So I probably would not be able to use my digital voice recorder programs or digital camera or printer in the 64bit version?

So to be on the safe side I should just use 32Bit?

You could use them; they just wouldn't make use of the 64-bit technology. So it could be a waste. You should look up whether or not some of your more cpu intensive programs are coded for 64-bit technology. Either send an e-mail to the company or try and find it on their website.

32-bit software works on 64-bit operating systems, just you won't see the performance increase.

I probably should of made that clear :-P

So what is on all these sites saying that the drivers would not work if they are not 64Bit drivers?

Almost all major companies supply both 32bit and 64bit drivers, so there shouldnt be many problems with compatability.

I found one exception recently- Line 6's Gearbox software has no 64bit support (ridiculous given the size of the company).

I assume your making this decision for your next computer. The vast majority of companies write drivers in 32-bit and 64-bit as the person above me said. Just look up on the manufacturer website for all the parts in your computer to see if they have 64-bit drivers too. If your buying a computer from say dell or toshiba & you choose a 64-bit Os with your new laptop or desktop they automatically put in hardware that has 64-bit drivers.

So your drivers need to be 64-bit to be able to use your computer with your OS and the programs that you run need to be coded for 64-bit technology to see any benefit, (if they're not you just won't get a performance increase they will still run).

64-bit computers allows you to send more data in and out in fewer times. Only problem is applications don't have that. I run XP 64, Vista x86, which I plan to up it to x64, and Linux x64. I have ditched the 32-bit environement for now.

Very good read..... also shows having 4gb with x32 is a good idea.
