C2D E4300 overclocks 
Athlon Classic, was the first x86 processor seventh generation and initially maintained its leading performance on Intel microprocessors. AMD Athlon continued using the name for its eighth-generation Athlon processors 64.
Core Classic Athlon processor launched the market on August 21, 1999. The first core Athlon, code-known as "K7" (in homage to his predecessor, K6), was initially available in versions from 500 to 650 MHz, but later reached speeds of up to 1 GHz processor is compatible with x86 architecture and must be plugged into Slot A motherboards that are compatible mechanically but not electrically, with Intel's Slot 1. Internally, the Athlon
is a redesign of its predecessor, which was substantially improved floating-point system (now 3 floating point units can work simultaneously) and was increased first-level cache (L1) 128 KB (64 KB for data and 64 KB for instructions). It also includes 512 KB of second level cache (L2) outside the integrated circuit processor and running, usually at half the speed of it (In the models most often the cache running at 2 / 5 [In the 750 , 800 and 850 MHz] or 1 / 3 [In the 900, 950 and 1,000 MHz] frequency of the processor). The communication bus is compatible with the EV6 protocol used in the 21264 DEC Alpha processor, running at a frequency of 100 MHz DDR (Dual Data Rate , 200 MHz effective).
result was the most powerful x86 processor time. The Athlon Classic was sold until January 2002.
In economic terms Athlon Classic was a success not only for its own merits and its low price compared with competitors, but also by production problems at Intel.
Core Thunderbird
Athlon processor core Thunderbird appeared on the market on June 5, 2000, as the evolution of Athlon Classic. Like its predecessor, is also based on the x86 architecture and uses the bus EV6. The clock speed range is from 650 MHz to 1.4 GHz Athlon Regarding the Classic, the Athlon Thunderbird Slot A change of the Socket A, smaller.
All Athlon Thunderbird up to 128 KB of cache first level (L1) (64 KB data and 64 KB for instructions) and 256 KB second-level cache (L2) on-die, of course running at the same frequency the nucleus. The manufacturing process used for these chips is 0.18μ (First made of aluminum interconnects and then in the 1 GHz or more, copper) and the package size is 117 mm 2 .
There are two versions of Thunderbird depending on the frequency of bus use. The first Athlon Thunderbird used a bus of 100MHz DDR (200 MHz effective), as well as the Athlon Classic . In the first quarter of 2001 new releases, called Athlon-C , supporting a bus of 133 MHz DDR (266 MHz effective).
The Athlon AMD Thunderbird consolidated as the second largest chip manufacturing company, and thanks to its excellent performance (always exceeding the Pentium III and Pentium IV Intel's first to the same clock speed) and low price , made it very popular among connoisseurs as insiders in the computer.
Athlon XP
When Intel released the Pentium IV 1.7 GHz in April 2001 was that the Athlon Thunderbird was not at his level. In addition it was impractical to raise the head remain in performance of x86 processors, AMD had to design a new kernel. so I get the athlon xp
Palomino core
launched the third major revision of the Athlon, known key as "Palomino", 15 May 2001. All from the core Athlon Palomino were known generically as Athlon XP. This processor was the desktop version of Athlon 4 processor, developed for laptops.
The main changes compared to previous core performance improvements were making it 10% faster than an Athlon Thunderbird the same clock speed. Its clock speed was between 1.3 and 1.7 GHz Palomino core was also the first to include the SSE instruction set of Intel, in addition to the 3DNow! AMD's own. The Palomino core still had problems with heat dissipation, which made it too hot. The improvements to the Palomino on the Thunderbird prerrecuperación we mention the hardware data, known in English as a prefetch, and the TLB entries increases from 24 to 32.
Due to performance improvements at the same clock speed compared to previous cores, the Athlon XP were sold not by clock speed, but with a rate "services relating" known as PR . This index indicates the equivalent clock speed of a core Athlon thunderbird with the same performance as an Athlon XP . For example, Athlon XP 1800 + actually runs to 1.53 GHz, but indicates that it has a performance equivalent to a hypothetical to 1.8 GHz Thunderbird
Thoroughbred core
The core of the fourth generation of the Athlon, the Thoroughbred , commonly referred to as "Thoroughbred" A "was released on June 10, 2002 at an initial speed of 1.43 GHz (1700 with the benefit system on.) Went on to achieve a 2800 + performance relative.
The core "Thoroughbred" was manufactured with a process of 0.13 microns, 0.18 microns to improve the manufacturing process "Palomino" core. Initially, apart improvement of the manufacturing process, the Palomino and Thoroughbred cores are virtually identical. Later
AMD created a review Thoroughbred core called "Thoroughbred-B" which solved the problems of heat dissipation from the core legacy Thunderbird.
Barton Core
The fifth-generation Athlon core, called Barton , operated at a rate PR from 2400 + - approximately 1837 MHz - and 3200 + - 2200 MHz -.
The Barton core was main characteristics regarding Thoroughbred to include a new second-level cache (L2) 512 KB and continue to improve processor performance without increasing clock speed. In addition AMD increased bus frequency of 133 MHz (266 effective for DDR) to 166 MHz (333 MHz effective) and then up to 200 MHz (400 MHz effective).
With the launch of the Athlon XP Barton core AMD again noted that its x86 processors were the fastest on the market, but some performance tests did not indicate this market. This caused a stir when it emerged that some of these tests as performance tests BAPCo were designed by engineers at Intel.
Thorton core
The core "Thorton" is a variant of "Barton", identical to this but with half of the second level cache (L2) off.
Mobile Athlon XP
The Mobile Athlon XP (Athlon XP-M ) are functionally identical to the Athlon XP, but work with lower voltages. They also have technology PowerNow! , which reduces the operating speed of the processor when workload is low, to reduce further consumption.
The Athlon XP-M
use the standard Socket A. Generally used in laptops.
The successor to the Athlon and Athlon XP (seventh generation) is the
Athlon 64 .
