AMD K7 is the code name of a microarchitecture of AMD. Unlike its predecessors, AMD K6 and AMD K5 AMD took advantage of the K7, similar to Intel with the Pentium, a full name - Athlon and related models - as the product name. The term therefore K7 is primarily for the Mikroachitektur this processor families, but is also partly used for the processors themselves.

Technical details

The K7 architecture is AMD's first completely redesigned CPU design, both in terms of the core itself as well as its infrastructure. So the bus protocol of the Alpha EV6 licensed, which allowed a much higher data throughput Front Side Bus.

In addition, the L2 cache has been similar to the AMD K6 -III, integrated in the processor. In the first models for the slot A of this has been realized with external chips on a processor board along with the actual processor, it was then integrated directly into the processor die.

The FPU has been greatly improved by the pipeline was used more efficiently ( "fully pipelined ").

Processors in the K7 generation

  • AMD Athlon (K7 )
  • AMD Athlon MP
  • AMD Athlon XP
  • AMD Athlon XP -M
  • AMD Duron
  • AMD Geode
  • AMD Sempron (K7 )


The K7 architecture laid the foundation for the successful K8 generation whose most famous member of the AMD Athlon 64.
