* Intel® Celeron® processors have been produced for a number of years, using several process technologies. Celeron processors manufactured after the introduction of the 130nm process will only be supported by the Intel® Processor Identification Utility, while those manufactured prior to the 130nm process will only be supported by the Intel® Processor Frequency ID Utility.

Pentium® 4 processors, and newer products manufactured after the introduction of the Pentium 4 processor, are identified with the Intel® Processor Identification Utility.

Pentium® III processors, and those products manufactured prior to the Pentium III processor, are identified using the Intel® Processor Frequency ID Utility.
