   Here you are:   
   john@Unifi-T9Pro:/sys/devices/system/cpu/cpufreq/policy0$   
     cat cpuinfo_max_freq   
     3400000   
      
   john@Unifi-T9Pro:~$ cat /proc/cpuinfo   
   processor	: 0   
   vendor_id	: GenuineIntel   
   cpu family	: 6   
   model		: 190   
   model name	: Intel(R) N95   
   ...   
      
   So what does that tell you?
