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 production yields. Each Athlon XP core that has a part of the L2-cache defective can be sold as Duron which the defective part disabled. > Read more

Except for production date and stepping, this CPU is identical to this AMD Duron 1800. > Read more

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

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
