INTEL PROCESSOR NUMBERS:

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.

^Combines Intel’s best mobile technologies, including the Intel® Pentium® M processor, Intel® 855 chipset family, and Intel® PRO/Wireless network connection.

† Hyper-Threading Technology requires a computer system with an Intel® Pentium® 4 processor supporting HT Technology and a Hyper-Threading Technology enabled chipset, BIOS and operating system. Performance will vary depending on the specific hardware and software you use. See http://www.intel.com/info/hyperthreading/ for more information including details on which processors support HT Technology.

Δ Intel processor numbers are not a measure of performance. Processor numbers differentiate features within each processor family, not across different processor families. See http://www.intel.com/products/processor_number/ for details.
