Here's two more:-

    root at garage:/etc/ssh# cat /proc/cpuinfo | grep 'model name'
    model name      : Intel(R) Core(TM)2 Duo CPU     E7400  @ 2.80GHz
    model name      : Intel(R) Core(TM)2 Duo CPU     E7400  @ 2.80GHz
    root at garage:/etc/ssh# cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_available_frequencies
    2800000 2133000 1600000 
    2800000 2133000 1600000 
    root at garage:/etc/ssh# 

    chris$ cat /proc/cpuinfo | grep 'model name'
    model name  : Intel(R) Core(TM)2 Quad  CPU   Q8200  @ 2.33GHz
    model name  : Intel(R) Core(TM)2 Quad  CPU   Q8200  @ 2.33GHz
    model name  : Intel(R) Core(TM)2 Quad  CPU   Q8200  @ 2.33GHz
    model name  : Intel(R) Core(TM)2 Quad  CPU   Q8200  @ 2.33GHz
    chris$ cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_available_frequencies
    2336000 2003000 
    2336000 2003000 
    2336000 2003000 
    2336000 2003000 
    chris$ 

ooh, and an older one:-

    chris at maxine:~$ cat /proc/cpuinfo | grep 'model name'
    model name      : Intel(R) Core(TM)2 CPU          6600  @ 2.40GHz
    model name      : Intel(R) Core(TM)2 CPU          6600  @ 2.40GHz
    chris at maxine:~$ cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_available_frequencies
    2400000 1600000 
    2400000 1600000 
    chris at maxine:~$
