Duron 900 based on the Spitfire core was a 32-bit x86 microprocessor developed by AMD and introduced in 2001. This model was part of the first series of the Duron family. Designed based on AMD's K7 (a Thunderbird-derivative) on a 180 nm process, this MPU operated at 900 MHz with a bus capable of 200 MT/s with a TDP of 39.5 W.
