How to Identify 32-bit or 64-bit Processors

idata — Fri, 27 Nov 2009 08:11:58 GMT

In Linux, we have a command "cpuid" which gives complete information about the CPU, it's starts somewhat like this.

Intel-specific functions:

Version 00000f47:

Type 0 - Original OEM

Family 15 - Pentium 4

Extended family 0

Model 4 -

Stepping 7

Reserved 0 ....

Everything is present except whether the Processor is 32-bit or 64-bit CPU. Is it possible to find out based on the above info. wheter a CPU is 32-bit or 64-bit. If so, how? I have seen numerous sites, but haven't got exact info. of how this could be found thorugh an OS, either Windows or Linux.

Thanks in Advance.

Regards

Adarsh

Hello,

There is a tool from Intel.

http://www.intel.com/support/processors/tools/piu/sb/CS-014921.htm

If Intel® 64 is yes, then it does support 64 bit processing.

Another way to check is to get the SL number of the CPU and check from the site below:

http://ark.intel.com

If you have got a 64 bit OS, you can just try to load the OS, it wont allow you to do so.

All the best,

Kind Regards,

Aryan.
