TheAMD K8 Hammer,alsocode-namedSledgeHammer, is acomputer processormicroarchitecturedesigned byAMDas the successor to theAMD K7 Athlonmicroarchitecture. The K8 was the first implementation of theAMD6464-bitextension to thex86instruction set architecture.[1][2]

Processors
editProcessors based on the K8 core include:
- Athlon 64- first 64-bit consumer desktop
- Athlon 64 X2- first dual-core ('X2') desktop
- Athlon X2- later model dual-core desktop with '64' omitted
- Athlon 64 FX- enthusiast desktop (multipliers unlocked)
- Sempron- low-end, low-cost desktop
- Opteron- server market
- Turion 64- mobile computing market
- Turion 64 X2- dual-core mobile processor
The K8 core is very similar to the K7. The most radical change is the integration of the AMD64 instructions and an on-chip memory controller. The memory controller drastically reduces memory latency and is largely responsible for most of the performance gains from K7 to K8.
Nomenclature
editIt is perceived by the PC community that after the use of thecodenameK8for theAthlon 64processor family, AMD no longer uses K-nomenclatures (which originally stood forKryptonite[3]) since no K-nomenclature naming convention beyondK8has appeared in official AMD documents and press releases after the beginning of 2005. AMD now refers to the codenameK8processors as theFamily 0Fhprocessors. 10h and 0Fh refer to the main result of theCPUIDx86processor instruction. Inhexadecimalnumbering, 0F(h) (where thehrepresents hexadecimal numbering) equals thedecimalnumber 15, and 10(h) equals the decimal number 16. (The "K10h" form that sometimes pops up is an improper hybrid of the "K" code andFamilyidentifier number.)
