This page will show all objects that classify as AMD Duron. The Duron has been made by Advanced Micro Devices, a multinational semiconductor that develops microprocessors, chipsets and graphic processors (ATi). AMD is the second largest microprocessor manufacturer after Intel and has active since 1969.
In 1982 AMD signed a contract with Intel to become a licensed second-source manufacturer. IBM wanted the Intel 8086/8088 but IBM's policy stated that at least two suppliers should be available. This is why the first AMD processors always have 'Intel' printed somewhere. After a while AMD didn't get the license to produce Intel processors anymore and thus AMD started cloning the 386 and launched the Am386. Since the AMD K5, AMD didn't clone the Intel processor but started developing on their own. The K5 wasn't a big success but thanks to NexGen that merged into AMD the K6 could be made. AMD could compete and has a range of processors today including six-core Opterons and a good performing quad-core for the desktop called the Phenom II X4.
AMD also acquired ATi to get in-house graphics chips. These are integrated in chipsets to create cheap motherboard solutions. In the future (The Future is Fusion as AMD calls it) the plans are to integrate the graphics chip into the processor.
AMD Duron 600 'D600AUT1B'
This is the slowest Duron AMD ever released. Technically it's an Athlon 'Thunderbird' but with less L2 cache. > Read more
A lot like this Duron 600 but 50MHz faster at a lower voltage. Technically (production wise) this chip is probably better and thus runs at a lower vCore (1,5V instead of 1,6V). > Read more
Just a normal Duron that fills up the gap between the 650 and 750 models.
Notice that this one doesn't have the four black pads in the each corner. Because I can see discoloration I know these pads were in place at one time. Why they are removed is unknown to me. > Read more
The AMD Duron 'Spitfire'. Quite a performer for a low price back then! The K7 architecture runs quite fine with very little cache. Because the (big!) L1 cache is inclusive the CPU still performs good. Cache intensive applicaties such as games are better off on an Athlon, though.
In the angled picture the modifications on the bridges on the CPU can clearly be seen. By closing the L1 bridges the multiplier will be unlocked. Closing all L11 bridges will result in 1,85V vCore. Tweaking and overclocking with a pencil, what do you want more?

Technically the same as this Mobile Duron 850 because it has the same 'Morgan' core. In this case it's a desktop CPU with a multiplier lock so the clock frequency can't move past 11x100MHz (1100MHz) unless you unlock the multiplier or adjust the front side bus (FSB) manually. > Read more
This is the fastest Duron AMD ever released. AMD stopped producing the Duron and started with Sempron for the budget class.
The 1400, 1600 and 1800MHz Duron are based on the Applebred core which is just a Thoroughbred B but with a part of the L2-cache disabled. AMD could use the defective Thoroughbred cores for Durons by disabling defective parts of the L2-cache. Some of the Durons did have fully intact L2-cache, however. Because the K7 architecture has a big L1-cache (128KB!) the CPU still performs good with little (64KB) L2-cache. On some older models (with different PCB) the L2-cache could be unlocked back to 256KB making it a full-blown Athlon XP 2200+. I even remember someone that took a Duron 1400, unlocked it and overclocked it to a whopping 3GHz!
Talking about overclocking: this CPU did 2,7GHz using watercooling which is not bad for a K7 CPU. > Read more
