What? The &quot;20&quot; was never the generation.<p>The i7-720, i7-820, and i7-940 are all Nehalem (ie first generation) core parts.<p>The numbering more or less makes sense if you prepend a 0 to the &quot;720&quot;. Now your generations make perfect sense.<p>Current desktop product codes still more or less make sense. Mobile is a complete clusterfuck though.
