AMD-K6-III/400ACK is a 32-bit x86 mobile microprocessor designed by AMD and introduced in late 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. This MPU dissipated a maximum of 16 W with a typical power dissipation of 12.6 W.
