Intel® processor numbers allow you to quickly differentiate among processors within a product family and make more informed decisions.

Processor numbers are based on a variety of features that may include the processor's underlying architecture, cache, front side bus, clock speed, power and other Intel technologies that enhance your experience.

Within a brand and processor family a processor number:
Represents a broad set of features that can influence the overall experience
Differentiates the relative features within a processor family (e.g. within the Intel Pentium® 4 processor family or within the Intel® Xeon® processor family
May indicate power- and performance-related features
Intel's processor number system is used with the following brands:

Intel® Pentium® processor Extreme Edition
Intel® Pentium® D processor
Intel® Pentium® 4 processor
Intel® Pentium® M processor2
Mobile Intel® Pentium® 4 processor - M
Intel® Celeron® D processor
Intel® Celeron® M processor

Guidelines

The processor number is not a measurement of performance, nor is it the only factor to consider when selecting a processor.

The digits themselves have no inherent meaning, particularly when looking across processor families. For instance, 840 is not "better" than 640 simply because 8 is greater than 6.

Furthermore, linear increments between processor numbers may not indicate linear feature advancements. For example, the differences in processor features between an Intel® Pentium® M processor 760 and an Intel® Pentium® M processor 765 will not be the same as between an Intel® Pentium® M processor 765 and an Intel® Pentium® M processor 770, even though both pairs of processors are separated by an increment of five digits.

Processor numbers do not represent specific system configurations and do not replace system-level benchmarks.
