AMD Athlon 64 FX processor and the standard Athlon 64 are the first 64-bit CPUs designed for desktop computers. AMD introduced Athlon 64 processor in 2003, in the same year Athlon 64 FX was also released with improved performance. Intel also launched their competing version – Pentium 4 Extreme edition in the same year.
Athlon processors are made based on the Opteron, a CPU designed specifically for workstations and server computers. When we come to the grouping, Athlon 64 FX is grouped into AMD’s K8 (eighth generation) processors series.
The key feature of both Athlon 64 and 64 FX is the integration of memory controller into the processor chip, which enables the processor to communicate directly with the memory and therefore reduce latency. This technology shortens the physical traveling distance of electrical signals. As a result the processor performance will increase greatly to the next level.
Both types of Athlon processors are available in four socket versions: Socket 940, Socket 939, Socket 754 and Socket AM2. The major difference between Athlon 64 and AMD Athlon 64 FX processor is memory bus widths and cache sizes configuration.
So far, AMD marketed several types of Athlon 64 FX processors: Athlon 64 FX-51, Athlon 64 FX-53, Athlon 64 FX-55, Athlon 64 FX-57, Athlon 64 FX-60, Athlon 64 FX-62, Athlon 64 FX-70, Athlon 64 FX-72 and Athlon 64 FX-74. Furthermore, Athlon 64 FX-60 and onwards, multi-core technology is incorporated in FX CPUs.
Purpose of AMD Athlon 64 FX processor
Athlon 64 FX processor was targeted those who want to have better performance regardless of its cost. Specifically, it was designed for gamers.
