Δ Intel processor numbers are not a measure of performance. Processor numbers differentiate features within each processor
family, not across different processor families. Over time processor numbers will increment based on changes in clock, speed,
cache, FSB, or other features, and increments are not intended to represent proportional or quantitative increases in any
particular feature. Current roadmap processor number progression is not necessarily representative of future roadmaps. See
www.intel.com/products/processor_number for details.
