AMD-K6-III/400AHX is a 32-bit x86 desktop microprocessor designed by AMD and introduced in early 1999. This MPU which was manufactured on a 0.25 µm process, based on K6-III microarchitecture, operated at 400 MHz with a bus of 100 MHz and a multiplier of 4. While default to a 100 MHz bus (Super 7), this model can also operate at the old Socket 7 bus speed of 66 MHz (multiplier of 6). This processors had a maximum power dissipation rating of 26.8 W.
