'''Duron 550''' based on the Spitfire core was a {{arch|32}} [[x86]] [[microprocessor]] developed by [[AMD]] and introduced in 2000. This model was part of the first series of the {{amd|Duron}} family. Designed based on AMD's {{amd|microarchitecture/k7|K7}} (a {{amd|Thunderbird}}-derivative) on a [[180 nm process]], this MPU operated at 550 MHz with a bus capable of 200 MT/s with a typical TDP of 25.4W.
