About Windows discharge.

Not so many computer users have heard that Windows has some sort of bit rate – x32, x64, and x86 – and even fewer users really know what it is, where it is, and why it is needed. Even some myths are related to these digit capacity.

Windows digit capacity is an icon of the article

Walking the other day on the Internet, I noticed an interesting thing – at least some clear information on this issue is quite small, which actually prompted me to write this article.

Introduction to Windows digit capacity

I will start with the fact that Windows has two bits so far: 32-bit and 64-bit, i.e. the distributions are divided into x32 and x64 correspondingly. But what about x86 is nothing more than a designation of the 32-bit version (i.e. if you see x86, you should know that it is x32). Why the two names are not clear but know that if you have not installed a 64-bit operating system specially, your Windows has 32-bit bits.

However, just in case, you can see the digit capacity in the system in the simplest way: find the shortcut “My Computer”, right-click on it and select the property item (the screenshot below is relevant for Windows 7, in case of Windows XP the window will be a bit different but the meaning is the same):

Let’s look at the difference between Windows x32 distributions and Windows x64 and whether it’s worth upgrading to 64 bits at all.

Note: not only the system but also programs (and drivers) have bits, i.e. there are 32-bit and 64-bit bits and therefore following the text below they can see and use either a limited amount of memory or the whole.

Is it worth changing the splint for soap and vice versa?

The main and perhaps the only difference between x64 and x32 is that the x64 version can handle up to 32 Gbytes of memory and run both 64-bit and 32-bit applications simultaneously while the traditional x32 can address only up to 4 Gbytes of memory, run only 32-bit programs for which only 3 Gbytes are available (to put it simply, even if the computer has 4 Gbytes (and more) of memory, the 32-bit system will display and work with only 3 Gbytes, while the rest of the memory will simply idle, for neither the system nor the programs will simply not see it).

The situation is different in the x64 version: for 32-bit applications, all the 4 (and more) Gbytes are available, and for 64-bit applications in general all the RAM that is physically installed in the computer. I repeat that a 64-bit system can launch both applications but not vice versa.

In general, this is the way it is. The rest is a lot of technical and not very detailed things which you need to know, so I’ll just give some results which will explain why стоит\не should (you should decide anyway) switch to x64.

Which Windows digit capacity to choose and why

Let’s go. All pros and cons of switching to Windows x64 digit capacity:

  • The 64-bit version of Windows formally looks and feels the same as the usual 32-bit one, i.e. there are no special innovations and bonuses in it, but people with multi-core processors may feel performance gain when using such a system and 64-bit applications in it (which is, however, relevant not for everyone and not always);
  • x64 is able to see and work with 4 Gbytes or more of memory. But x32 can see only 3 Gbytes even if the physical memory plank costs more. That is, people who have a large memory reserve in their computer will get more performance on a 64-bit system and fewer problems with memory shortage;
  • Not for all the computers and iron in it, the manufacturers have released 64-bit versions of drivers which may become a problem when porting to such a system. Check availability of drivers at the site of manufacturers of mat.boards, video cards, etc. It is possible that you just cannot migrate from a 32-bit system;
  • Most x32 applications work fine on x64 systems, but not the other way around;
  • Formally, the point of migrating is mainly the amount of memory on board the computer. If it is less than 4 Gbytes, there is almost no sense in migrating. If it is more (or you want to put more), you should. Naturally, for most systems, applications and games the rule “The more memory – the better” is relevant. Why? Read in my article “Practice of using 8 GB of RAM + WD VelociRaptor in RAID 0”.
  • My opinion is definitely x64, because a lot of memory and, sometimes, improved performance for multicores definitely rules.

Briefly, somehow.
