Athlon and was
The original Athlon ( now called Athlon Classic ) was the first seventh-generation x86 processor and, in a first, retained the initial performance lead it had over Intel's competing processors for a significant period of time.
This means that at 100 MHz, the Athlon front side bus actually transfers at a rate similar to a 200 MHz single data rate bus ( referred to as 200 MT / s ), which was superior to the method used on Intel's Pentium III ( with SDR bus speeds of 100 MHz and 133 MHz ).
Whereas the AMD K6-III + topped out at 570 MHz due to its short pipeline, even when built on the 180 nm process, the Athlon was capable of clocking much higher.

Although the Athlon was multiplier locked, crafty enthusiasts eventually discovered that a connector on the PCB of the cartridge could control the multiplier.
In commercial terms, the Athlon " Classic " was an enormous success — not just because of its own merits, but also because Intel endured a series of major production, design, and quality control issues at this time.
It was sold at speeds ranging from 600 MHz to 1. 4 GHz ( Athlon Classics using the Slot A package could clock up to 1 GHz ).
With the older Athlon CPUs, the CPU caching was of an inclusive design where data from the L1 is duplicated in the L2 cache.
In October 2000, the Athlon " C " was introduced, raising the mainboard front side bus speed from 100 MHz to 133 MHz ( 266 MT / s ) and providing roughly 10 % extra performance per clock over the " B " model Thunderbird.
The Athlon XP-M was also offered in a compact microPGA socket 563 version for space constrained applications as an alternative to the larger Socket A.
As Athlon XP-M CPUs were already rated running lower voltages than their desktop siblings, it was a better starting point for lowering voltage even further.
It was released on June 19, 2000 as a low-cost alternative to AMD's own Athlon processor and the Pentium III and Celeron processor lines from rival Intel.
The Duron was pin-compatible with the Athlon and carried all of the computational resources from it, operating on the same motherboards in most cases.
The original Duron was limited to operating on a 100 MHz front-side bus speed ( FSB 200 ), while the Athlon at the time could run on a bus clock of 133 MHz ( FSB 266 ).
It was based on the 180 nm " Thunderbird " Athlon core.
The second-generation Duron, the " Morgan " core, was sold in speed grades between 900 and 1300 MHz, and was based on the 180 nm " Palomino " Athlon XP core.
The final generation Duron was called " Applebred ", sometimes called " Appalbred ", and was based on the " Appaloosa " Duron along with the 130 nm " Thoroughbred " Athlon XP.
Duron's biggest difference from Athlon was its reduction in cache size to 64 KB, in contrast to the 256 KB or even 512 KB of Athlon.
AMD's Duron " Spitfire " CPU was only roughly 10 % slower than its big brother, Athlon " Thunderbird ".
With a basic chip configuration modification, it was found that " Applebred " could be turned into " Thoroughbred B " Athlon XPs, with full 256KB cache, with a very high success rate.

AMD Athlon ( early version )-another technically different, but fully compatible, x86 implementation.
For example, the Intel Pentium and the AMD Athlon implement nearly identical versions of the x86 instruction set, but have radically different internal designs.
AMD even ended up playing a significant role in directing the evolution of the x86 platform when its Athlon line of processors continued to develop the classic x86 architecture as Intel deviated with its " Netburst " architecture for the Pentium 4 CPUs and the IA-64 architecture for the Itanium set of server CPUs.
) In the x86 architecture it was implemented by AMD, as NX bit, for use by its AMD64 line of processors, such as the Athlon 64 and Opteron.
