Core name(s)

The AMD K8 is a computer processor microarchitecture designed by AMD as the successor to the AMD K7 microarchitecture. The K8 was the first implementation of the AMD64 64-bit extension to the x86 processor architecture.

Processors based on the K8 core include:

The K8 core is very similar to the K7. The most radical change is the integration of AMD64 instructions and an on-chip memory controller. The memory controller drastically reduces memory latency and is responsible for most of the performance gains from K7 to K8.
