The CPUID Data section of the utility identifies Intel processors by reading a precise instruction embedded in the processor.

The CPU Technologies section of the utility reads the internal registers of the processor to identify and display the Intel processor technologies that the processor supports. The utility then informs the user of the overall system status as a result of this comparison. The utility then examines internal data in the processor and makes a comparison between this data and the operating frequency it measured. The Frequency Test section of the Intel Processor Identification Utility runs a frequency determination algorithm (speed test) to determine at what internal speed the processor is running. The Intel Processor Identification Utility is not intended to identify microprocessors manufactured by companies other than Intel. The Web Update feature enables updating to the latest version of the Intel Processor Identification Utility.The Save feature enables the processor information to be saved into a text file.The CPUID Data section of the utility identifies the Intel processor(s) in the system.The CPU Technologies section of the utility displays the Intel processor technologies and features present in the selected processor.The Frequency Test section of the utility provides information regarding the operating status of the selected processor.
