Intel® Processor Numbers

Make informed decisions

Once you have decided on the processor brand family that is right for you, Intel processor numbers allow you to quickly differentiate among processors within that product brand family. The 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.

A processor number:

Represents a broad set of features that can influence overall computing experience
Differentiates the relative features within a processor brand family (e.g. within the Intel® Core™2 processor family or within the Intel® Xeon® processor family)
The processor number is not a measurement of performance
Is one of several factors, along with processor brand, specific system configurations and system-level benchmarks, to be considered when choosing the right processor for you.

Intel's processor number system is used with the following brands:

Intel® Core™2 Extreme processor Intel® Core™2 Quad processor Intel® Core™2 Duo processor Intel® Core™ Duo processor Intel® Core™2 Solo processor Intel® Core™ Solo processor	Intel® Pentium® processor Extreme Edition Intel® Pentium® D processor Intel® Pentium® dual-core processor Intel® Pentium® 4 processor Intel® Pentium® M processor¹ Mobile Intel® Pentium® 4 processor Intel® Celeron® Dual-Core processor Intel® Celeron® D processor Intel® Celeron® M processor Intel® Celeron® processor	Intel® Xeon® processor 7000 sequence Intel® Xeon® processor 5000 sequence Intel® Xeon® processor 3000 sequence Intel® Itanium® processor

It is important to know that linear increments between processor numbers don't necessarily reflect feature advancements. That is why once you have decided on a particular processor brand and type, you should then use the processor number to verify that a specific processor version has the features you are looking for.
