We call them ‘modelizers’

Tom’s Hardware Guide notes that future Athlon processors will be specified by a model number, rather than megahertz: “For instance a Palomino-Athlon that runs at 1.4 GHz will be MODEL 1600, because AMD considers Palomino 1.4 GHz to be at least as fast as a Pentium 4 1.6 GHz. The printing on the chip will be ‘A1600 …..’, even though its a 1400 MHz part only. The same is valid for motherboards and their POST. A new BIOS Writer’s Guide prohibits the BIOS from ever displaying the true core frequency of Palomino! It has to display the MODEL number instead.”
