title: How can I find out what "processor family" an Intel processor is under?
body: <p>In the Intel manual, there are tables containing listings of <code>Performance-Monitoring Counters</code>, but they are extremely specific to the particular processor family.</p>
  
  <p>For example, one table lists the counters of <code>P6 Family</code>, and another lists for <code>Pentium</code>.</p>
  
  <p>In <code>Ubuntu</code>, if I do <code>cat /proc/cpuinfo</code>, I get a line that says <code>cpu family</code>, but it is a single number. Is there some mapping between this number and Intel's notion of a <code>processor family</code>?</p>
  
  <p>I also looked <a href="http://www.intel.com/content/www/us/en/processors/processor-numbers.html" rel="noreferrer">this page</a> from Intel, but it does not even mention the word "family".</p>
  
  <p>Incidentally, I am on an <code>X3470</code> so I thought maybe <code>Xeon</code> was the family, but the manual does not list it.</p>
