32 Bit or 64 Bit which Windows 7 is Best for you ?

which one should you choose when you install your Windows 7.

This question has been raised numerous times in forums as well as between potential customers. I have seen most of the time the sellers are not able to explain the differences between 32 bit and 64 bit to the buyer, making it more confusing.

If you are planning to buy a new computer or going to Install Windows fresh and don’t know which edition to choose, than following is a brief overview of Windows 7 32 bit (x86) editions and Windows 7 64-bit (x64) editions.

  1. System Requirements:
    This is the most important issue to be considered first, if you are planning to install 64-bit edition of Windows. In order to use 64 bit operating system you must have a 64 bit Processor (As of now all new processors sold are 64 bit). However, even if you have a 64 bit processor, you can still install 32-bit operating system, not necessarily 64-bit. But you can not install a 64-bit windows edition in a 32-bit processor system.
  2. RAM (Random access Memory) Limitations: 32-bit operating systems have some limitations, they can support only up to 4 GB of Physical RAM. Which means even if you have more memory (Physical) installed in your system, 32-bit operating system will be able to utilize only 4 GB of RAM(3.2 GB to 3.7 GB) and the rest will just be wasted. This is not a Windows specific limitations, but the 32-bit architecture itself can not access more than 4GB of RAM. However this is not the case with the 64-bit architecture of Windows, for example Windows 7 Basic users can use up to 8GB of RAM, 16 GB for Windows 7 Home Premium users and a whooping 192 GB for Windows 7 Professional/ Ultimate /Enterprise users.
  3. Driver Compatibility: Drivercompatibility is one of the significant issue between these two editions of Windows. Many device manufacturers (hardware) did not release 64-bit drivers for their devices, even after 64- bit processors were already in use.

    Which means many devices (prior to 2006) like, printers,scanners, cameras, may not work correctly or not at all under Windows 7×64. If you still have such devices you will need to check the manufacturer website and download the 64-bit drivers. Newer generations of devices come with both 32 bit and 64 bit drivers.

  4. Software Compatibility: Prior to Windows Vista and Windows 7, Windows XP completely dominated, as far as number of Windows users around the world. Here is the problem, while most of the software available today is 32-bit, the processors we buy are almost all 64-bit. Not all software’s that worked under windows XP will work with windows 7, this issue will specially effect the Windows basic/Home users. However almost 98% of all the software which works with windows 7 32 bit will also work with windows 7 64 bit, without any decrease in performance or reliability.

    The main reason is that the newer 64-bit systems are backward-compatible with 32-bit systems. However, Applications which deeply integrate themselves with the Operating system, like your Antivirus , Firewall software’s, you will have to install the correct version to be compatible with your 64-bit windows operating system.

  5. Performance : The architecture of 64-bit computing is designed to give a superior performance specially for tasks which involve large amount of computations, like in graphics editing, gaming, video editing/ encoding etc. However this performance benefit can be seen only if the program is specifically optimized for 64-bit use.Thus programs like Photoshop x 64 and AutoCAD x64 versions would show a definite performance increase by utilizing the full potential of the 64-bit computing power.

  6. Windows 7 DVD generally includes both 32-bit and 64-bit versions of the windows and you are given the choice to install, right at the beginning of the windows installation.So before you proceed to select which architecture you would like to install make sure that your system have 64-bit processor.

  7. Upgrading: You must note that it is not possible to upgrade your system from 32-bit operating system to 64-bit operating system and vice versa.If you want to upgrade your 32-bit windows 7 to 64-bit windows, than you must format your hard disk and re-install your operating system from scratch.

    Conclusion: The Computer is a very complex machine. There are several Items that normally, you don’t concern yourself about.One such item is “Data buss” it provides transportation, which also means it connects memory to the rest of the system including the processor, which does all the thinking, calculating in your computer.

    This “Data buss” is used to move data inside your computer.In a 32-bit architecture the size of this Data buss is 32 bit wide. In a 64-bit architecture this “Data buss” is 64 bit wide, twice more then 32-bit, so the system can move twice as much data around. Being able to process more data means a Faster system.But this advantage will benefit only some applications like graphic processing, Video encoding etc. Your normal Office productivity and web surfing will show no added advantage at all

So Next time if you decide to buy a new Machine or Upgrade your Operating System, go for the Windows 7 64 bit architecture. I would suggest you to go for Windows 7 Professional or the Windows 7 Ultimate version, to get the maximum benefit windows 7 has to offer.
