Difference between Vista x64 and x86?

When you see XP x64 or Vista x64, it money the 64-bit versions of these operating systems. When you see x86, it technique the entire family of IBM-compatible PC's, built on a 286/386/486 CPU (and very soon, of course, adjectives the generations of pentium processors).



-best luck
Vista x64 can address a larger amount of RAM.

Vista x64 is totally incompatible near 16bit software.

While Vista x64 can run most 32bit software, you will probably find incompatability issues with some programs - for example VMware server.

Vista x64 requires signed drivers, and these drivers are harder to procure for Vista x64 than other operating systems.

When 64 bit programs become more common surrounded by a few years, Vista x64 will be able to run them. At the moment really few exist.



Unless you are goign to have a huge amount of RAM (over 4 gb) surrounded by your system, go for 32bit Vista.
They run on different CPUs. x86 uses 'words' that are 32 bits long to process instructions surrounded by the chip. x64 uses 'words' that are 64 bits long. You need a 64 bit CPU to run Vista x64.
vista x64 is for 64-bit pc's while x86 is for 32-bit pc's.

not every system supports 64-bit architecture.

my notebook supports x64 but still i use the 32-bit version of window vista ultimate as it is much faster than x64.

and also every hardware and software supports x86 while near are some compatibility issues with the 64-bit reworked copy.
