Many users, and ask ourselves, and we question how editors choose Windows Vista: 32 - or 64 bit - bit? Well, try to answer this question and determine pluses and minuses of each option.

Let's first find out that there are and from which went architecture. x64 - a technology developed by AMD (AMD64), in order to quietly and painlessly for the end user to move from the 32 - bit x86 world (286 - 386 - 486 - compatible microprocessors) to a new 64 - bit era of computer calculations. Intel, in partnership with HP has refused to extend the ancient x86 platform and established its own 64 - bit architecture Itanium IA-64. Because was fundamentally different from the predecessor, its ability to emulate the x86-based applications have been, to put it mildly, weak. Intel had hoped that the market fairly quickly adapt new platform, but literate path for migration was not much. Itanium therefore did not receive wide distribution. AMD decided to extend the x86 architecture has a proven new 64 - bit capabilities by adding processor in the 64 - bit registers. This option was adopted at the market hurrah. As a result, Intel copied the AMD64 architecture (pursuant to a contract AMD-Intel on cross-licensing), and named it EM64T. Both x64 technology, in general, are identical, except for minor differences in hardware implementation.
Microsoft has released 64 - bit version of Windows XP, and gave her the name of simple Windows XP 64-bit Edition. This operating system has been set up to IA-64 Itanium has been fully 64 - bit, but with the help of emulation supported and 32 - bit applications. Moreover, for the IA-64 and was a special version of Windows 2000 Server. The problem was unhurried adaptation of IA-64, but when AMD has established AMD64 and Intel had no choice but also how to follow the example, Microsoft has developed a x64 version of Windows XP, a version of it, and Windows Server 2003. 64-bit versions were hybrid type, because to execute and 32 - bit and 64 - bit code without the need for software emulation, while Windows XP x64 Edition for the execution of 32 - it is such a bit of code emulation to be de rigueur.

However, with the release of Microsoft Windows Vista company simultaneously released two versions: 32 - bit x86 and 64 - bit x64. Boxed versions of Windows Vista Ultimate contain both editorial OS, but OEM versions can contain either one or the other - before an order is necessary to determine. Therefore, the question "What editor choose Windows Vista - 32 or 64 - bit" took on special importance.
The first thing to do is - check that your chosen processor supports 64 - bit instructions. If you do not know for sure, that is a small utility - x64 detector, which will test the ability of your CPU.

A brief overview of modern processors:
Almost all AMD or Intel servers are sold in the past two years have supported x64
Most desktop processors high-end, as of AMD, and from Intel, released over the past year have opportunities x64 -
More expensive models Sempron processors are supported x64; cheaper - no
Processors AMD Durons do not support x64
All AMD Opteron processors are supported x64
All processors from AMD X2, and Athlon64 FX have supported x64
All Intel Pentium D processors and Celeron D are supporting x64
Mobile AMD Turion processors are supported x64
Intel Core 2 (mobile, desktop and server) are supporting x64
Mobile Intel Core Duo processors do not support x64
Mobile Intel Pentium M processors do not support x64.
Poor x64 place - drivers
Second, what is worth paying attention - to check whether all devices are available x64-quality drivers, and no matter whether they are in the OS or can be downloaded from the site of the device manufacturer. From this perspective, many of motherboards have problems with sound, and network drivers. Therefore, please visit the manufacturer you use chipset. Drivers, for example, for network cards Gigabit LAN and audio drivers to support 5.1 sound can be found here. NVIDIA also released new drivers. ATI (AMD) is not lagging behind competitor - you can get the latest version of the drivers. Creative Only a few days ago, has finally been issued 64 - bit versions of their drivers. Luckily, many manufacturers have already fired drivers for the major components of a computer, but there are no drivers for peripherals. So on , printers, and other devices crawlers can be forgotten. At least for now.

X drivers (Note are due to peripheral devices) for the 32 - bit Windows Vista problem is not likely to arise. But when it touches x64, it is emerging problems. From this point of view x64 version is because many of the usual devices simply will not work. Making work on the basic components of the system easily, but there are always one or two devices that namertvo stoporyat all attempts to force them to work the user. For this reason, few computer manufacturers solved predustanovit 64 - bit version of Windows Vista, because in the current situation, support for 64 - bit system - a veritable hell and night nightmare for the producers.

Serwer, on the other hand, are not required peripherals, and they tend to work with a limited set of devices. Everyone respects a manufacturer of the server hardware, offering, for example, adapters HBA Fiber Channel or iSCSI should give full support to x64. Microsoft Exchange Server 2007, for example, is available only in the 64 - bit version, and soon many manufacturing companies intend to issue on 64 - bit versions of their software products.
Professional workstations - another candidate for the 64 - bit operating systems, because it is x64 provides maximum performance and speed. For example, a free utility for editing images optimized for Multi systems, and to the same fully x64-compatible. But Adobe is not going to produce even 64 - bit version of Photo shop CS3 coming. This does not mean that you can not run the 32 - bit version of Photoshop, in fact, in Windows x64 application is likely to be slightly faster, because x64 is available in more than 4 GB of RAM. Let Adobe will be embarrassed because, in its annex Paint.NET 64 - bit reincarnation shows huge gains in productivity - from 50 to 100%. Adobe worthwhile to support x64 couple of years ago, however, the company does not intend to do so in the next year.

The conclusion is that the implementation of migration, you should carefully assess your computer hardware limitations. If all of the available devices correctly you are working in Windows Vista x64, it advances - 64 - bit computing will open up new horizons for you.
