List of AMD CPU microarchitectures

The following is a list of AMD CPU microarchitectures.


It is perceived by the PC community that after the use of the codename K8 for the Athlon 64 processor family, AMD no longer uses K-nomenclatures (which originally stood for Kryptonite[1]) since no K-nomenclature naming convention beyond K8 has appeared in official AMD documents and press releases after the beginning of 2005. AMD now refers to the codename K8 processors as the Family 0Fh processors. 10h and 0Fh refer to the main result of the CPUID x86 processor instruction. In hexadecimal numbering, 0F(h) (where the h represents hexadecimal numbering) equals the decimal number 15, and 10(h) equals the decimal number 16. (The "K10h" form that sometimes pops up is an improper hybrid of the "K" code and Family XXh identifier number.)

Family Hex (h) number Decimal number Codename Reference
Family 0Fh 15 K8 / Hammer
Family 10h 16 K10
Family 14h 20 Bobcat
Family 15h 21 Bulldozer
Family 16h 22 Jaguar
Family 17h 23 Zen

The Family hexadecimal identifier number can be determined for a particular processor using the freeware system profiling application CPU-Z, which shows the Family number in the Ext. Family field of the application, as can be seen on various screenshots on the CPU-Z Validator World Records website.
