What is Athlon XP?

Athlon XP processors are truly a whole family of processors. This family now includes five models with slightly different cores.

The very first processor of the Athlon XP family is made using 0.18 micron technology; its feature is the QuantiSpeed ​​architecture. We will not go into the subtleties of this architecture now. The change in architecture allowed us to significantly increase the performance of processors (compared with previously released processors on the Thunderbird core, which raised a real storm in the processor market). It was at this time that a designation was introduced that was not related to the actual clock speed of the processor. These processors had individual numbers (CPUID) 660, 661, 662, etc. However, what is the difference between processors with different CPUIDs, now hardly anyone will remember, but this is probably not important anymore. More importantly, with this core, the processor clock frequency was only raised slightly more than 1700 MHz.

The next step was made with the advent of Athlon XP processors on the Thoroughbred core (CPUID 680). These processors began to be produced already at 0.13 micron technology. With the advent of these processors swept the first wave of disappointment. It was expected that with the transition to 0.13 micron AMD technology will certainly break out into absolute leaders. But it turned out that the Athlon XP 2200+ processor, which had appeared very first, had become a number of quite ordinary processors by the time of its appearance. The wave of disappointment was primarily due to the fact that too much was expected. The core of the processor remained almost the same, only it was implemented using new technology. More importantly, it was theoretically possible to further increase the processor clock speed. In fact, everything went not so smoothly. The first processor, made using the new technology, Athlon XP 2200+ (core clock frequency 1800 MHz) was also the fastest processor in the series with CPUID 680. Subsequent processors of this series had only a lower frequency.

To raise the processor clock speed, a redesign of its core was required. Modified processors are also called Athlon XP, the core is still called Thoroughbred (sometimes Thoroughbred-B), only the CPUID has changed. The clock frequency of the processor core with CPUID 681 reached 2133 (Athlon XP-2600). Since a further increase in the processor clock speed without increasing the bus bandwidth does not lead to a proportional increase in performance, a new processor upgrade has appeared with the same core and the same CPUID, but with an effective bus speed of 333 MHz. These processors have reached the core clock frequency of 2167 MHz (Athlon XP 2800+)

And now the long-awaited processor on the Barton core has appeared. Athlon XP 3000+ is now the most powerful AMD processor, although its core clock speed is only 2167 MHz. The increase in performance was achieved due to the increase in the volume of the second level cache to 512 MB.
In this regard, it will be very interesting to determine the actual performance of these processors and compare it with the actual performance of Intel processors. This will be the answer to the question, “with what results does AMD end the era of 32-bit processors?”

Who needs these 64 bits?
On September 23, the new 64-bit processors from AMD, Athlon 64 3200+ and Athlon 64 FX-51 were officially announced. However, Internet users have long been familiar with these processors, since…
