Compare editions: 64-bit editions of Windows Vista

Understanding 64-bit PCs

If you've gone PC shopping lately, you've probably noticed more computers with 64-bit processors, and you may have wondered what advantages they offer.

Put simply, a 64-bit PC can handle larger amounts of information than a 32-bit system. Since it can use more RAM—4 GB and up—a 64-bit computer can be more responsive when you're running lots of programs at once.

Windows Vista supports both 32- and 64-bit software.

What should you do?

Like most shopping decisions, the choice between a 32-bit and 64-bit PC comes down to a little research and balancing your priorities. Here's what we recommend:

  1. Look for the logo
    Check to make sure that the hardware and software you want to use with it is compatible. You'll find that most of the hardware devices and software programs you use today will work well with 64-bit editions of Windows Vista. The best way to know if something will work is to look for the Windows Vista logos on devices and software programs—that means they're compatible with both 32-bit and 64-bit editions of Windows Vista.

  2. Visit the Windows Vista Compatibility Center
    If you don't see the logo, visit the Windows Vista Compatibility Center and check the 64-bit compatibility status.

  3. Balance your priorities
    If your first priority is having a PC that can take advantage of increased memory and new hardware or software, then lean towards a 64-bit PC. On the other hand, if cost is a key concern and you're mostly interested in running a couple programs, or if you have older hardware and software that isn't supported by a 64-bit PC, then a 32-bit PC is a good choice.
