AMD Duron D700AST1B 700MHz Socket A 462 Spitfire 64KB L2 Cache CPU Processor

AMD Duron D700AST1B 700MHz Socket A 462 Spitfire 64KB L2 Cache CPU Processor

The AMD Duron D700AST1B is a 700MHz desktop processor built on AMD's Spitfire core (Model 3), designed for Socket A (Socket 462) motherboards. It runs a 200MHz front-side bus with a 7x clock multiplier, operates at a 1.5V core voltage, and includes an integrated floating-point unit. Packaged in a 453-pin staggered ceramic PGA (CPGA) form factor, it is compatible with any Socket A motherboard supporting the Duron processor family.

Applications

The AMD Duron was introduced in mid-2000 as AMD's budget-oriented Socket A processor, competing directly with Intel's Celeron line. It used the same Athlon core architecture and Socket A platform, making it a cost-effective entry into the Athlon ecosystem. The Spitfire core Durons were manufactured on AMD's 180nm process and were widely used in budget desktop builds, small office systems, and educational computing during the early 2000s. Today, Duron processors are sought after by collectors and enthusiasts maintaining vintage Socket A systems, retro gaming rigs, or period-correct PC builds from that era. Compatible motherboards include those using chipsets such as the VIA KT133, AMD 750/760, and SiS 730/735.
