What Kind of Processor for Windows Vista?
Microsoft's system requirements for Windows Vista specify that a processor with a minimum speed of 800 megahertz (MHz) is needed to run the Vista Home Basic operating system and a minimum speed of 1 gigahertz (GHz) is required for all other editions. Vista supports 32-bit (x86) and 64-bit (x64) processors.

Variants
-
Windows Vista is available in 32-bit and 64-bit variants. 64-bit versions of Vista are capable of supporting more physical memory (RAM) than 32-bit versions. If you wish to use a 64-bit version, you will need a 64-bit processor. You can also run standard 32-bit Windows Vista on computers with a 64-bit processor.
Due to potential compatibility issues you should always ensure all your hardware and software is compatible with 64-bit Windows Vista if you choose to use it.
Capabilities
-
If you have a processor with multiple cores, all versions of Windows Vista can support this capability. However, if you have a computer with more than one physical processor installed, note that only Windows Vista Business, Ultimate and Enterprise editions support dual processors.

Considerations
-
Check system requirements for your software and peripherals if you are choosing a processor to use with Windows Vista. Certain applications and devices may require a faster processor than the operating system to function effectively. This is especially relevant to graphics packages and games.
Compatibility
-
Various processor socket formats exist. You must ensure you choose a processor compatible with the socket on your motherboard, which will be specific to either Intel or AMD compatible processors.
Recommendation
-
The system requirements for Vista were defined at its time of release. As of March 2011, most processors run at speeds way in excess of the original recommendations. A processor only meeting the minimum specifications is unlikely to deliver good performance, so choose a modern processor for best results.
