Before comparing with competing processors, let’s look at the performance of Athlon XP processors with different CPUIDs.
The model number is simply the number of a specific model in the Athlon processor family. This is AMD’s official position and investing any other meaning in this figure is hardly a sign of special literacy. The model number is calculated from the set of tests. Continue reading
Despite the variety of generally accepted tests, recently their results have often added confusion than to clarify the essence of the phenomena.
There are tests that allow you to measure the performance of a computer subsystem, for example, the speed of data exchange between a processor and memory or cache. These tests are necessary in order to find out the impact of individual technical solutions, more precisely, to understand why a particular processor is better or worse than others. But the practical sense in these tests is quite small. Continue reading
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).

On April 22, AMD announced a server version of its 64-bit Opteron processor. Unfortunately, the server version was announced. In addition, most likely at the beginning the 64-bit platform will be very expensive, so for a long time we will continue to install 32-bit Athlon XP processors in desktop computers. Information about the Athlon XP processors, and especially about its latest modification (on the Barton core) is very contradictory. Continue reading
First of all, it must be emphasized that in the AMD64 architecture, the main attention was paid to the issue of compatibility with 32-bit applications that are widespread now. The new processors are fully compatible with 32-bit (generally speaking, even with 16-bit) applications. Compatibility is achieved due to the fact that the AMD64 architecture is an extension of the x86 architecture. The registers existing in the x86 architecture are expanded to 64 bits, while the lower 32 bits of each register can be used by 32 bit applications in the same way as in the x86 architecture: Continue reading
