Discussion about bits on CPU

As we know out there is:

8 bit devices  and even basekine core devices (12 bit)

16 bit bit devices

32 bit devices

64 bit devices

128 bit devices etc.

and lets say that device speed is 1 Hz it would be:

8 bit devices 1 Hz = 8bit/sec

32 bit devices 1 Hz= 32bit/sec  etc.

and if those device speed would be 1 GHz than results might be:

8 bit devices 1 GHz = (8*8*8*8..30 times)bit/sec

16 bit bit devices 1 GHz = (16*16*16*16*16.. 30 times)bit/sec

So I'm asking question above of all this am I right about this stats. Please comment what you know about this subject.
