| Processor Number Nomenclature System |
Going forward, Intel processors will be named using a combination of the processor brand (the "processor family") and a specific 3-digit number (the "processor number").
Example:
Processor numbers will be categorized in 3-digit numerical sequences such as 7xx, 5xx, or 3xx. This number plus the processor family comprise the overall "processor name". Within each number sequence are specific processor numbers such as 735, 560, or 320. References to the clock speed in the processor name (as has been used in the past) will be replaced with the processor number, which now represent a broader set of features that influence the overall user experience. Processor families may also change to reflect changes in Intel's product offerings.
Examples of specific Intel processor families include:

| * The Intel® Pentium® M processor is the processor component of the Intel® Centrino™ brand, which also encompasses a mobile chipset and integrated wireless LAN capability. |
All processor families have their own unique value proposition and correspond to differing usage models for the end customer. Once customers decide how they wish to use their PC, they can select a processor family (brand) based on their desired computing experience. In that context, processor numbers can then be used as a guide in determining what combination of features is most preferable.
A higher number within a processor family can indicate more processor features, more of a specific processor feature, or a change in architecture. Note that in some cases, a higher number processor may potentially have more of one feature and less of another.
For example, there may be a case where the processor number increments due to a front side bus increase (e.g. from 400 MHz to 533 MHz), or cache increase (e.g. from 512KB to 1MB), even though the clock speed may stay constant or decrease. When comparing processor numbers, it's important to keep in mind that there are other key features outside of clock speed that contribute to the overall value of the processor.

| Processor Number Guidelines |
Processor numbers should be used to differentiate between the relative overall features within a certain processor family (e.g. within the Intel® Pentium® 4 processor family) and within a numbering sequence (e.g. 550 vs. 540). However, the digits themselves have no inherent meaning, particularly when looking across families; e.g. 710 is not "better" than 510 simply because 7 is greater than 5 from a numerical perspective. The numbers are aligned with different processor families and thus represent different value propositions to the end customer.
Processor numbers are also not a measurement of performance. A higher number does not necessarily mean higher performance for any given usage model or any given system configuration. Tools are available to end customers wishing to evaluate processors from solely a performance-based perspective. In these cases, the customer may refer to industry-standard benchmarks which measure PC performance while running specific end user applications. Processor numbers do not represent specific system configurations but rather a set of available processor features, and therefore cannot be used as a proxy for system-level benchmarks.
