A clean looking AMD Duron. Note that it never had the four rubber pads on each side to prevent the heatsink from tilting during installation.

Mechanical samples usually appear like a real CPU but often don't work. I never tested mine (there is a risk of burning the CPU and/or motherboard) but it ... > 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

This is the slowest Duron AMD ever released. Technically it's an Athlon 'Thunderbird' but with less L2 cache.... > 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.

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

A somewhat uncommon AMD Duron 700 because of it's low vCore. It only needs 1.4V where most Duron 700's were shipped out with a 1.6V requirement.

AMD started with the first Duron's at 600MHz that often needed 1.5V or 1.6V. As the clock-frequency went up the need for a bit more vCore also went up. ... > Read more

I always thought that the slowest/first Duron 'Morgan' ran at 1000MHz, until I saw the original specification from AMD which also mentioned a 900 and 950MHZ model. However, it took about 14 years for me to see a 900MHz Duron with Morgan core!... > Read 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 b... > Read more

An uncommon CPU. Most Duron's at 900MHz are based on the Spitfire core (which is the budget version of the Thunderbird core). When AMD shifted to the Palomino core (for use in their Athlon XP processors) they also created the Morgan core for the new Duron processors. Often you'll only find Morgan CP... > Read more

The fastest breed of the Morgan-based Duron's. These CPU's ran quite well back in the day and paired up with DDR-SDRAM memory and a decent harddrive it was easily faster than a vastly more expensive Pentium 4.... > Read more

The slowest Duron of the new 'breed' Applebred. See this Duron 1800 for more info about these CPU's.

The middle of the last Duron-breed. The last Duron 'Applebred' came in 1400, 1600 and 1800MHz models. This model has the same clock-frequency as the Athlon XP 1900+ but less L2-cache enabled. AMD uses the same 130nm 'Thoroughbred' cores for the Duron (but gives it the name 'Applebred') to increase p... > 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 Thoroug... > Read more
