AMD K6x (K6 K6-2 K6-3 and mobile variants) ID guide
The AMD K6 family of CPUs comes in MANY versions with varying core voltages, temperature ratings and packages. This guide will help you establish which version of the CPU you have. It is also useful in finding what CPUs you want or need for your collection. Please note that the speeds marked on mobile chips are maximum speeds. This is due to the speed scaling used to increase battery life. It is not a true 'Performance Rating' as the chips actually ARE capable of running at the speed (and do when running on AC).
