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:
- Athlon 64
- Athlon 64 X2
- Athlon 64 FX
- Sempron
- Opteron
- Turion 64
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.
