32bit vs 64bit OS

Yeah everything works, haven't really encountered any issues whatsoever, with Windows 7 64-bit.

False, it uses the Dunia engine which is a heavily modified version of the first CryEngine. Crysis uses the CryEngine 2 engine.

P.S. There is no FarCry 2 with a 64bit installer or conversion patch for it, it is still 32bt as such.

CryEngine 3 FTW :p

I switched to 64bit in Feb this year. All perfomance definately shot up! I can use all of my CPU's cores and my RAM. The one thing I have noticed is that, It hasn't frozen or crashed like the 32bit used to do. Gaming certainly improves.

64bit No Doubt!!!!

I agreed..

64x is really the way to go..

I mean I remembering myself asking MYBB the same questions.. and someone said the x64 is the future.
and if you want to have 4GB+ you must have 64x..

You think in multimillion dollar company's that handles money and use a wide variety of programs....... they will use a 64 bit OS.
Ok i could be wrong but what are banks using nowadays.

64bit is more secure in it's build but how does the bank sector automatically relate to office applications? It would only make sense for them to move to 64bit if they were buying new computers but other than that they should be ok with 32bit for the time being I suppose. The point is that most 32bit applications do run on 64bit, I'm not sure who would still be running 16bit programs these days but those are the ones you have to be wary about not running at all.

What's the point there is no real benefit for switching to 64bit. It will only cost a lot of money.

When you buy the retail pack of Winows 7 you do get 32bit and 64bit included, so how would it cost a lot of money? Even with laptops with Windows 7 can upgrade to 64 bit with their 32bit keys. I'd recommend it on the the purchase of a new PC to remove the hassle of upgrading separate components in an old PC which would constitute as the lots of money you are talking about.
 
To add to the debate...Windows 7 can address your GPU memory as part of the system memory, which means it has to be added to the total. 64bit is the way to go.

Thats true in a way but not the whole story. 32 bit Windows also does this, believe it or not.

This involves what is called an address space, as well as memory mapped IO. An address space refers to all addressable memory in your system. It doesnt necessarily refer to system memory, because of memory mapped IO. So, your system address space includes your system memory and memory mapped IO.

Memory mapped IO is a technique of assigning an address from your system address space to a system component such as graphics card memory. It allows easier access to that particular system component.

The problem comes when your maximum address space in 32 bit is 4GB. You still need memory mapped IO, but now that goes at the end of the address space, meaning you now cannot address the last few hundred megs of system memory - those addresses are now used by memory mapped IO. In contrast, because a 64 bit system has so much more memory, you can address all of your system memory and still have enough left over for memory mapped IO. So it allows you to have your cake and eat it basically, because the system address space is so much bigger.

Sounds very complicated.. But you know.. I think you just mean that x64 takes alot more ram than x32 it self.. ^ ^

I heard that x64 can go up to something 1TB of ram.. but I don't know.. it's not like someinthg like that is real.. to us now.. :P

It cant support a lot more memory, yes. The exact amount will differ by motherboard and operating system, but with 64 bit systems its usually pretty high. Not sure about the TB range.

64 bit can support 2^64 bits of memory, which is quite a bit. Windows can only see around 192GB though (depending on the OS version). Also the intel I7 processor, for example, have a 64 bit instruction set, but only a 36bit memory extension, limiting the RAM to 24GB....
 
Last week I bought Win 7 to put on my new Apple core i7 laptop, to run as a secondary OS under parallels - so I can still use some of my old Windows apps. I opened the box and was greeted by both 64 bit and 32 bit disks. Well it was a no-brainer for me, I had plenty of RAM and processor power, so I installed the 64 bit. I then proceeded to download around 500 MB of stuff I needed, antivirus etc. Then when I loaded my windows apps that I really need to run, I found out that they will only run under 32 bit Win 7, and that there will be no support for 64 bit.

So, I need the easiest way of downgrading my OS to the 32 bit version. Sure, I can delete the 64 bit version and do a clean instal of the 32 bit, but it means copying all the stuff I have now put onto the 64 bit, deleting, reinstalling......Can I not just put the 32 bit disk in, and it will automatically downgrade me, and keep all my apps and programs ? Thanks I.A
 
You can't downgrade, sorry, you have to do the re-install thing. I'm surprised, what apps weren't compatible? I have actually not had any issues with W7 64-bit.
