AMD Duron processor is a low-cost CPU based on the K7 architecture. The first generation of Duron processors used Spitfire core, which is similar to the Athlon Thunderbird core with the exception of L2 cache - the Duron had 64 KB L2 cache while the Athlon had 256 KB cache. Having larger L1 cache, faster bus speed and more powerful FPU unit, the Duron Spitfire processors significantly outperformed their competitors - Intel Celeron processors with 66 Mhz FSB. Even after the bus speed on Celeron processors was increased to 100 MHz, they were still lagging behind the Duron CPUs.

The Spitfire core Durons were produced in speeds up to 950 MHz. Faster AMD Duron processors used a Morgan core. Like the Spitfire core is similar to the Thunderbird core, the Morgan core takes most of the features from the Athlon Palomino core. The core was tweaked for greater performance by implementing a full set of SSE instructions, adding a data prefetch mechanism and increasing the size of the Translation Look-aside Buffer.

The next Duron core - Applebred - was used in the last three processors from the Duron family. In these processors the bus speed was increased to 266 MHz, and the core voltage was reduced to 1.5V. The Applebred core was the last Duron core - the Duron CPU family was phased out in favor of new AMD Sempron family.

Production microprocessors

The first Duron core was very similar to Athlon Thunderbird core, except that the size of L2 cache was slashed from 256 KB to 64 KB. Reduced L2 cache size resulted in slightly lower performance of Durons - they were on average 5% - 10% slower than Athlons at the same frequency. However, first Duron processors were significantly faster than their direct competitors - Celerons. For example, Duron 600 was almost always faster than Celeron 766, and often as fast as Celeron 800.

Starting from Duron 1GHz all Duron processors had new core that was based on Athlon Palomino core. This core added data prefetch mechanism and support for SSE instructions. These features helped to improve performance of Duron Morgan processors in SSE-enabled and memory-intensive applications, making the Morgan core on average a few percent faster than the Spitfire core. Still, this performance gain was not sufficient to beat equally clocked Athlon Thunderbird processor (which didn't have data-prefetch and SSE instructions).

Visually it's easy to distinguish Duron processors with Palomino core from microprocessors with Spitfire core - Palomino die is narrower and taller. Even though the Palomino die may look larger, it's only slightly larger than the Spitfire die - 106 mm2 as opposed to 100 mm2. Both cores have approximately the same number of transistors - 25.2 million transistors for Palomino, and 25 million transistors for Spitfire Durons.

DHD1400DLV1C was the first AMD Duron microprocessor with Applebred core. This core was manufactured using more advanced 0.13 micron process as compared to 0.18 micron for older Spitfire and Palomino processors. Applebred Duron processors had lower core voltage and lower power consumption than older Durons. For example, this Duron 1400 had the same typical power consumption as Duron 1100 with Palomino core.

AMD Boxed cooler is to bad

The AMD Duron Boxed cooler is not keeping the cpu at 50-70 Celcius. My duron don`t survivd that temperature. My rubber feets it`s also broken.
