    How to Identify 32-bit or 64-bit Processors

    AdarshBravo

      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.
