  • Win7 32bit or 64bit?

    Hello,

    I have a 64 bit processor and was wondering if I should install windows 7 32bit or 64bit. Would it make a difference in a carputer environment?

    generally, 64bit is not good for carputing because most home-brew apps and plugins that you are likely to use will only work in 32bit. pretty much the same reason that, at least right now, its still best to use winxp over vista or 7.

    only reason one might go for 64bit would be if they had a high performance gaming carpc. but even then you might as well dualboot, unless you dont plan on using a lot of specialized software.

      Thanks, that's what I thought. But more likely to use win7 32 over winxp.

        Right now, 50% of Windows 7 PCs bought by consumers are 64 bit. Gartner estimates that 75% of Windows 7 installed will be 64 bit by 2013.

        The writing's on the wall for 32-bit, and the sooner people quit installing it, and start reporting any 64-bit bugs to software maintainers, the sooner we'll all be better off.

        Seriously. Install 64-bit, see if all your software works. If it does, great. If not, submit bugs to upstream. It'll probably work.

          But you see, most application we use in the carputer are 32bit, ie: winamp, GPS software, iGuidance, Dashcommand, google earth, firefox, webcam software, all 3rd party plugins for winamp, roadrunner, centifuge, etc...
          Can you name me a single 64bit application that we use in the carputer? I can't think of any...

          A 64bit OS is only good if the software (application) takes advantage of the 64bit bus.

          64bit OS has been around for more than 5 years now, and winamp has yet to release a 64 bit version of their popular player. Why? For such a popular player, I don't know why.

          Even though we see a lot of 64bit application coming out now, the 32bit version will always be available.

          Now unless you are planning to do some word processing or image editing in your car, then you can use office 64bit or photoshop 64 bit along a 64bit OS.

          I don't see the need to install a 64bit OS in the car, although it does not hurt. But I am also worried about compatibility issues that may arise with 32 bit application.

            I would go with 32bit, because its what is standard right now. Some people run 64bit, but I dont know what hardware and software they run, like FE wise.

            Agreed, its all done in 32bit so I would stay with 32bit. I do not agree with using XP over Win 7 though. Vista was a big $h!++y OS, so never even consider it. As far as Win 7 though, there are so many advantages to using it. Only disadvantage is that some stuff that is made for XP, even though updated to Win 7, still may not work like it did on XP. Thing is the Pro over Win 7 over XP out weigh the cons.

            In my setup I am using Win 7 32bit for the main system. The second system, because it uses legacy graphics cards, I decided to use XP. Because the second system doesnt need hybrid sleep like the main system, I really didnt mind XP. Also, because I am a newbie with Win 7, and the second system is using Extended Windows to create 6 different user environments, I felt better with XP, because I have done it with XP before.

            I agree, 64bit is the way to go, soon. i think in about 2 more years, we will be forced to go 64bit. I would love to take advantage of my 64bit processors. I also like the fact that there is a huge increase in how much RAM we can use. 32bit can only use 4GB max (technically 3.25GB). Both boards I have have the ability to support 8GB of RAM, and I am forced to use 4GB.

              if you use xport it wont work on 64bit windows. Other than that i've had no problems running anything.

                Have you needed to use xport with Win 7 64bit though? I have a few devices that are 32bit based and the drivers barely work on XP. I can get them to work in Win 7, but will they also work in Win 64 bit?

                  I own GPSGate, which does the same thing xport does but works with 64bit OS. I havent run into any devices which dont work with 64bit, GPS, TPMS, fusion brain, spacenav.. they all work either native or with 32bit compatibility mode

                    This is looking a lot like when we switched from 16 to 32 bit. It took a while and we tossed old hardware and software that didn't make the change. There were some nice things that didn't run well on WoW32 emulation. Just like everything running on WoW64 now. It's a little like underclocking the CPU but it stays just as hot.

                    But it's kind of a chicken/egg thing. Running everything on emulation is a disadvantage, but without high enough demand there won't be any pressure to make the switch.

                      A 64bit OS is only good if the software (application) takes advantage of the 64bit bus.
                      Aside from any factual weirdness about applications caring about the width of the bus itself... This is incorrect.

                      The OS can access more memory and handle it faster, even if one app can't [PAE blows]. The OS and select apps can do more things at the same time, even if one app can't. Microsoft even claim it's more secure.

                      64bit OS has been around for more than 5 years now, and winamp has yet to release a 64 bit version of their popular player. Why? For such a popular player, I don't know why.
                      Because it runs just fine on 64-bit? Why do they need to build two binaries right now when one works fine? Sooner or later it'll stop working; as I said, half of windows 7 installs globally right now are 64-bit. Nullsoft are faced with the question; either get their stuff working, or take an immediate cut in potential customers by fifty percent.

                      And you know what? If they don't support it, get another mp3 player. There are lots out there.

                      Even though we see a lot of 64bit application coming out now, the 32bit version will always be available.
                      No. How many people build 16-bit windows software nowadays? How many people release universal binaries for OSX, let alone PPC-specific ones?

                      Admittedly there's a question of timing, but sooner or later people will be looking at 128 bit machines as rinkydink and the holdouts will be saying "Even though we see a lot of 256bit applications coming out right now, the 128bit version will always be available".

                      But it's kind of a chicken/egg thing. Running everything on emulation is a disadvantage, but without high enough demand there won't be any pressure to make the switch.
                      Exactly. You know how right now, everyone kvetches how IE6 is some kind of terrible thing that we all need to stop using, yet people are still using it?

                      This 32-to-64 bit thing is the same; at some point, there'll still be people using it because software they use targets it, which only targets it because they use it.

                      At this point, what everyone *should* do, but of course won't, is go 64-bit on their next install. Any applications that don't work, you submit bugs and stop using. Xport, for example; as already stated, gpsgate replaces it.


                      In the end, Joel covered this better than I could: http://www.joelonsoftware.com/items/2008/03/17.html. I fall firmly on the idealist side, which I feel I can afford to because I'm a software developer and a long term Linux user, from back when Linux sucked; through copious amounts of personal experience, I can confidently state that
                      1) Getting my code running on 64 bit has never been a problem. Developers who find it's a problem shouldn't be allowed near a compiler.
                      2) I can get along fine without piece_of_software_X if the developer doesn't want me to use his stuff. There are always replacements

                        For most user level code it's just a matter of clicking on 64 bit target and work out any compiler errors, and as far as I know they don't even need to be running 64 bit. But a lot of us kernel level writers have quite a bit more work to do and more stuff to buy. It's a big load for the hobbyists. Even some of the larger companies are just finally getting drivers out, and they have $2000/yr MSDN subscriptions and development computers that they can crash, so some of us will take a little longer to catch up.

                          I'll give you that kernel development is a fair bit different, but anyone using anything in their car PC that requires kernelspace voodoo should seriously reconsider their choices.

                          The companies that are only just getting drivers out are the ones that have by now been tangibly impacted by their lack of support. And I laugh.

                          Sniglet for today: In order to get the "Windows 7 Certified" sticker for a pc, every item in it must be supported under 64 bit Win7 [I think my WHQL-certified, but I'm not sure]. So all those companies who are only just releasing 64-bit drivers are the ones whose hardware isn't currently being put in dells, gateways, etc. Thus I laugh at their shortsightedness that led to their loss of profits.

                            did you guys forget where talking about carPCs not traditional computing?

                            lets take a quick look at pros and cons:
                            Pros:
                            * more addressable memory space (>4GB or 3.5 if you want to talk real world)
                            * slightly faster 64bit floating point math (video encoding, scientific calculations, encryption)
                            * memory mapped file support >4GB

                            Cons:
                            * Larger application footprint
                            * larger memory footprint
                            * incompatibilities with 32bit applications, libraries and some drivers
                            * requires context switching when running 32bit and 64bit code
                            * larger code uses more CPU cache which can result in some calculations executing slower then 32bit

                            now we boil that down to whats relevant in a carPC:
                            pros:
                            * None
                            cons:
                            * larger memory footprint
                            * incompatibilities with 32bit applications, libraries and some drivers
                            * requires context switching when running 32bit and 64bit code
                            * larger code uses more CPU cache which can result in some calculations executing slower then 32bit

                              LOL. XPort, GpsGate, and other drivers are voodoo? There are hundreds of hardware drivers, minidrivers, upper/lower/mid class, filter drivers, file system drivers, USB, WDM, bluetooth, port, miniport, video, audio, HID drivers running in kernel space on your car PC doing all kind of things you don't need to know about but are required and even your software relies them.
