Uniform Speed Term for PC's, like dB's

How fast is your CPU? It is expressed in Megahertz, one Hertz is a cycle one second long named after the magnet pioneer Heinrich Hertz, God knows that man loved his magnets and their properties. Anyhoo, I was wondering why my CPU is rated in clock cycles using Hertz. The CD-Burner is rated 16X which is 16 times faster than playback rate of a music CD. I think. This is a self referential spped term the likes of which are used by salesman to impress us. The Front Side Bus speed is in MegaHertz, the Ethernet too (1ooMhz). I remember a term call the FLOP which stood for Floating Point Operations per Second, I heard it used to describe a Sun workstation. The term itself flopped.

I want a standard speed definition for every aspect of computing: CPU, memory, bus, network, CD burners everything and across every platform: Mac, PC or Sun.

I'm think the deciBell, summertime Caper and good Scot he was, Bell. The term dB is a relative measurement (where I think dBm is a referenced measurement?). Anyway I am reading up on the deciBell or dB. It measures loudness, or loss or gain.

So could there be a term to cover all PC devices regarding speed? Like, I would say, "My new PC is 3.4 deciKen's, how fast is your mac?".
