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.
Note: The Specification Updates for the Pentium
®
processor, Pentium
®
Pro processor, and
other Intel products do not use this convention.
