'''AMD-K6-III/400AFR''' is a {{arch|32}} [[x86]] desktop microprocessor designed by [[AMD]] and introduced in early [[1999]]. This MPU which was manufactured on a [[0.25 µm process]], based on {{amd|microarchitectures/k6-iii|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 18.1 W.

== Cache ==
{{main|amd/microarchitectures/k6-iii#Memory_Hierarchy|l1=K6-III § Cache}}
[[L3$]] can be 512 KiB to 2 MiB, depending on manufacturer and [[motherboard]] model. L3$ is off-chip.
