I had already written about find out CPU speed and type in Windows or Linux system. Now Intel has released an updated version of its Processor or CPU Identification Utility. This utility can be used to verify that you have purchased correct CPU.
The Intel Processor Identification Utility was developed by Intel Corporation to identify the processor inside a system, assuring the processor contains intended technologies and is operating at the tested and rated frequency intended by Intel Corporation.
There are two versions of the utility available. The Windows version of the utility can be used with systems that support the Windows operating system environment. The “Bootable” version of the utility does not require an operating system. You can boot from computer floppy disk.
