4. 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.
